Best AI Tools for Excel, Google Sheets & PDFs in 2026

Best AI Tools for Excel, Google Sheets & PDFs in 2026

AI tools for Excel can make spreadsheet work much easier, especially when you are dealing with formulas, large datasets, charts, or repetitive tasks. Instead of spending hours searching for the right formula or manually checking hundreds of rows, you can use AI to analyze your data and explain what is happening.

The same idea now extends beyond spreadsheets. AI tools can also help you work with Google Sheets and long PDF documents, making it easier to find information, summarize reports, compare documents, and answer questions about files.

But which tool should you actually use?

Some AI tools are better for Excel formulas and spreadsheet analysis. Others are designed for Google Sheets, while some are much better at reading and researching long PDFs.

In this guide, we’ll compare the best AI tools for Excel, Google Sheets, and PDF analysis in 2026. We’ll look at what each tool does well, who should use it, and which option makes the most sense for different tasks.

There is no single winner for everyone.

If you spend most of your time in Excel, Microsoft Copilot may be the most convenient choice. If you use Google Sheets every day, Gemini makes more sense. For general file analysis, ChatGPT is a strong starting point, while Claude and NotebookLM are especially useful for long documents and research.

1. ChatGPT — Best Overall AI Tool for Excel and PDFs

ChatGPT is one of the most flexible options if you want a single AI tool for different types of files.

You can use it to analyze spreadsheets, work with CSV files, ask questions about PDFs, summarize documents, create tables, and explore data.

OpenAI currently supports common spreadsheet files such as XLSX and CSV for data analysis, along with PDF files. ChatGPT can also perform calculations and create visualizations from uploaded data.

What can ChatGPT do with Excel?

There are many practical uses for AI tools for Excel, and ChatGPT covers several of them.

For example, you can ask ChatGPT to:

  • Explain an Excel formula
  • Create a formula from a plain-English description
  • Find trends in a dataset
  • Identify unusual values
  • Summarize sales data
  • Compare two datasets
  • Create charts
  • Clean or reorganize information
  • Calculate percentages and averages
  • Explain what your spreadsheet is showing

Instead of searching online for a complicated formula, you can describe what you want.

For example:

“Create an Excel formula that calculates the percentage change between January and February sales.”

You can then ask the AI to explain the formula so you understand what it is doing.

ChatGPT for PDF analysis

ChatGPT can also be useful when you have a long PDF that you don’t want to read from beginning to end.

You can ask questions such as:

“Summarize the main findings of this report.”

Or:

“Find the three biggest risks mentioned in this document.”

This can save time when working with reports, research papers, business documents, or other supported files.

Who should use ChatGPT?

ChatGPT is a good choice if you want one tool that can handle both spreadsheet and document tasks.

It is especially useful for freelancers, students, researchers, marketers, and small-business owners.

Best for: Overall file analysis
Main strength: Flexible and easy to use
Downside: You should still verify important calculations and conclusions.


2. Microsoft Copilot — Best AI Tool for Excel Users

If Excel is already part of your daily workflow, Microsoft Copilot is one of the most logical AI tools to try.

The biggest advantage is that Copilot can work within the Microsoft ecosystem instead of requiring you to constantly move files between different applications.

Microsoft documents several Excel capabilities, including finding trends and outliers, generating formula columns, creating summaries, and working with charts and PivotTables.

What can Copilot do in Excel?

Depending on your account and available features, you can use Copilot to:

  • Analyze spreadsheet data
  • Find patterns
  • Identify unusual values
  • Generate formulas
  • Explain formulas
  • Summarize data
  • Create charts
  • Ask questions about your spreadsheet
  • Explore business data using natural-language prompts

For example, instead of manually looking through monthly sales figures, you could ask:

“Which region had the highest sales growth this year?”

That is much easier than manually sorting several columns and calculating the changes yourself.

Why Excel users may prefer Copilot

The main benefit is convenience.

If your work already happens inside Microsoft Excel, an AI assistant built into that environment can reduce the need to switch between different tools.

Microsoft also provides Analyze Data functionality in Excel, which allows users to ask questions about their data and receive visual summaries and insights.

Who should use Copilot?

Choose Copilot if you work with Excel regularly and want AI assistance inside your existing spreadsheet workflow.

Best for: Microsoft Excel users
Main strength: Deep Excel integration
Downside: Feature availability depends on your Microsoft 365 plan and account.


3. Gemini — Best for Google Sheets Users

If you use Google Sheets instead of Excel, Gemini is worth considering.

The biggest reason is simple: your files and productivity tools are already inside Google’s ecosystem.

For people who work with Google Drive, Google Sheets, and Google Docs every day, staying inside that environment can be more convenient than moving files to a separate AI platform.

What can Gemini help with?

Depending on your Google Workspace setup, AI features can help with tasks such as:

  • Understanding spreadsheet information
  • Generating formulas
  • Organizing data
  • Summarizing information
  • Finding patterns
  • Creating content from spreadsheet data
  • Working with information across Google Workspace

This makes Gemini particularly useful for people who collaborate through Google Sheets.

Who should use Gemini?

If your business, school, or freelance workflow is based around Google Workspace, Gemini is a natural option.

You don’t necessarily need the tool with the longest feature list. Sometimes the best choice is simply the one that fits your existing workflow.

Best for: Google Sheets and Google Workspace
Main strength: Google ecosystem integration
Downside: Features vary by account and subscription.


4. Claude — Best for Long Documents and Detailed Analysis

Claude is particularly useful when the problem is not just numbers but a lot of information.

Imagine you have a long research report, technical document, business proposal, or PDF containing dozens of pages.

You may not want a short summary. You may want to ask several questions and understand how different parts of the document connect.

That’s where Claude can be useful.

Claude for PDF analysis

You can interact with documents conversationally.

For example, you could ask:

“Explain the main argument of this report in simple English.”

Then follow up with:

“What evidence does the author use to support that argument?”

You can continue asking questions instead of repeatedly searching through the document manually.

Claude for spreadsheet analysis

Claude can also help with spreadsheet-related tasks such as analyzing data, explaining formulas, and reasoning through complicated datasets.

However, if you want AI directly inside Excel, Microsoft Copilot may be more convenient.

Claude makes more sense when understanding and reasoning about information is the main goal.

Best for: Long documents and complex analysis
Main strength: Detailed conversational reasoning
Downside: Not as deeply integrated into Excel as Copilot.


5. Julius AI — Best for Spreadsheet Data Analysis

Julius AI takes a more specialized approach.

Instead of trying to be an AI assistant for everything, it focuses heavily on working with data.

You can use a tool like Julius when you have datasets that need to be explored, analyzed, or visualized.

What can you analyze?

Typical use cases include:

  • Sales data
  • Customer data
  • Survey results
  • Marketing reports
  • Financial datasets
  • Business performance
  • Other structured datasets

The advantage of a dedicated data-analysis tool is that the workflow is focused on the data itself.

For example, you could ask an AI tool to identify the strongest-performing products and then explore why those products are performing better.

Who should use Julius AI?

Julius is worth considering if spreadsheet and dataset analysis is a regular part of your work.

If you only occasionally open an Excel file, a general-purpose tool such as ChatGPT may be enough.

Best for: Dedicated data analysis
Main strength: Data-focused workflow
Downside: Less useful if your main need is document research or general AI assistance.


6. NotebookLM — Best for Researching Multiple PDFs

NotebookLM is especially useful when you have several documents about the same subject.

For example, imagine you are researching a topic and have:

  • Five research papers
  • Two reports
  • A textbook chapter
  • Several PDF notes

Reading everything separately can take a lot of time.

NotebookLM lets you build a source-based workspace and ask questions about the information in those sources.

What makes this useful?

You can ask questions such as:

“What conclusions do these reports agree on?”

Then:

“Where do the researchers disagree?”

And:

“Create a short summary of the main recommendations.”

This type of workflow is particularly useful for research.

Who should use NotebookLM?

NotebookLM is a strong choice for students, researchers, analysts, and anyone who regularly works with multiple documents.

Best for: Research and multiple PDFs
Main strength: Source-focused document analysis
Downside: More specialized than a general AI chatbot.


7. ChatPDF — Best for Quick PDF Questions

Sometimes you don’t need a complete research system.

You simply have a PDF and want answers.

That’s where ChatPDF-style tools can be useful.

The workflow is straightforward:

Upload your PDF → ask a question → get an answer.

You could ask:

  • What is this report about?
  • What are the main findings?
  • What methodology was used?
  • What are the limitations?
  • Where is this topic discussed?
  • Summarize this document in five points.

Who should use ChatPDF?

It is useful for people who regularly receive PDFs and want a quick way to understand them.

Students, researchers, employees, and business users can all benefit from this kind of workflow.

Best for: Quick PDF questions
Main strength: Simple and focused
Downside: Less versatile than a general AI assistant.


8. Adobe Acrobat AI Assistant — Best for PDF Workflows

Adobe Acrobat is already a popular tool for opening, editing, and managing PDF documents.

Its AI features add another layer by allowing users to interact with PDF content using natural language.

What can it help with?

Depending on your plan and available features, you can use Acrobat’s AI capabilities for tasks such as:

  • Summarizing documents
  • Asking questions
  • Finding information
  • Understanding long PDFs
  • Extracting useful information
  • Working with document content

The biggest advantage is that you can keep your PDF workflow inside Acrobat.

If you’re already using Acrobat for work, adding AI may be more convenient than moving documents into another application.

Best for: PDF workflows
Main strength: PDF management plus AI
Downside: Some advanced features require eligible paid access.


What Can AI Tools for Excel Actually Do?

AI is much more useful in Excel than simply generating formulas.

Here are some practical ways you can use it.

Generate Excel formulas

You can describe what you want in normal language and ask AI to create the formula.

For example:

“Create a formula that calculates the percentage change between two monthly sales figures.”

This is especially helpful when you know the result you need but don’t remember the exact Excel syntax.

Explain complicated formulas

If someone sends you a spreadsheet with a formula you don’t understand, AI can explain it step by step.

This can be particularly useful for beginners.

Analyze spreadsheet data

You can ask AI to identify:

  • Highest-performing products
  • Best sales regions
  • Monthly trends
  • Unusual changes
  • Missing information
  • Relationships between columns

Instead of looking at thousands of rows manually, you can start with a high-level analysis.

Clean messy data

AI can also help you identify common data problems, such as inconsistent names, duplicate entries, missing values, or formatting issues.

However, always review the result before replacing your original dataset.

Create charts and summaries

AI can help turn raw spreadsheet data into a more understandable summary.

For example:

“Create a summary of this year’s sales performance and highlight the biggest changes.”

That can give you a useful starting point for a report or presentation.


What Can AI Do With PDFs?

PDF analysis is another area where AI can save time.

Summarize long PDFs

Instead of reading every page immediately, ask AI for a short overview.

You can then decide which sections deserve closer attention.

Ask questions about a PDF

You don’t need to search manually for every answer.

Ask:

“What are the main recommendations in this report?”

or:

“What does the document say about customer retention?”

Extract information

AI can help find specific dates, names, figures, recommendations, or other details inside long documents.

Compare documents

When the tool supports multiple sources, you can compare reports and identify similarities and differences.

Create research notes

A long research paper can be turned into a more manageable set of notes covering:

  • Main argument
  • Key findings
  • Methodology
  • Important statistics
  • Limitations
  • Conclusions

This doesn’t replace reading the original source, but it can make the first pass much faster.


Best AI Tools for Excel vs Google Sheets vs PDFs

The important thing is to choose based on your actual workflow.

If you’re already comfortable with Excel, there may be little reason to move everything into another platform just to use AI.

Likewise, if your entire workflow is in Google Workspace, Gemini may be more convenient than a separate spreadsheet tool.


Are AI Tools for Excel and PDF Analysis Free?

Some AI tools offer free access, but free does not always mean unlimited.

You may encounter limits on:

  • Number of messages
  • File uploads
  • File size
  • Advanced models
  • Daily usage
  • Data analysis features
  • Workspace integrations

This is why you should check the current plan before choosing a tool for regular work.

A free plan may be perfectly fine for occasional use. However, someone analyzing spreadsheets every day may quickly run into usage limits.

Also remember that free access can change. AI companies frequently update their plans and features.


How to Get Better Results From AI Spreadsheet Analysis

One of the easiest ways to improve AI results is to stop using vague prompts.

Weak prompt

Analyze this Excel file.

The AI doesn’t know what you’re actually looking for.

Better prompt

Analyze this sales spreadsheet. Find the three regions with the highest revenue, compare their monthly growth, and point out any unusual changes.

That’s much clearer.

A useful prompt structure is:

Context + Task + Conditions + Output

For example:

“This spreadsheet contains monthly sales data. Identify the products with the fastest growth, ignore rows with missing sales figures, and present the results in a simple table.”

You don’t need complicated prompt engineering.

Just tell the AI what the file contains, what you want to know, and how you want the answer presented.


How to Get Better Results From PDF AI Tools

The same idea applies to PDFs.

Instead of:

Summarize this PDF.

Try:

Summarize this report in 10 bullet points. Focus on the findings, statistics, recommendations, and limitations.

Or:

Compare the recommendations in sections 3 and 5 and explain any important differences.

Specific questions usually produce more useful answers.


Are AI Tools for Excel Accurate?

They can be very useful, but you should not blindly trust AI-generated results.

This is especially important when working with:

  • Financial data
  • Business reports
  • Research
  • Tax information
  • Customer records
  • Important calculations

AI can misunderstand a column, make a calculation mistake, overlook missing data, or draw a conclusion that isn’t supported by the dataset.

Microsoft also recommends reviewing and verifying AI-generated results when using Copilot.

So treat AI as an assistant, not the final authority.

Keep your original file.

Check important formulas.

Verify important numbers.

And when analyzing a PDF, compare important claims against the original document.


Which AI Tool Should You Choose?

Here’s the simplest recommendation.

Choose ChatGPT if:

You want one flexible AI tool that can work with spreadsheets, PDFs, questions, summaries, and data analysis.

Choose Microsoft Copilot if:

Excel is where you spend most of your working day.

Choose Gemini if:

You mainly use Google Sheets and Google Workspace.

Choose Claude if:

You frequently deal with long documents and need detailed explanations.

Choose Julius AI if:

Data analysis is the main reason you’re using AI.

Choose NotebookLM if:

You’re researching several PDFs or other source documents.

Choose ChatPDF if:

You want quick answers from individual PDF files.

Choose Adobe Acrobat AI Assistant if:

Your PDF workflow already happens inside Acrobat.


Final Verdict

The best AI tools for Excel are not necessarily the same tools that are best for PDF analysis.

For most people who want one flexible solution, ChatGPT is a strong overall choice. It can work with spreadsheets and PDFs while also handling many other everyday tasks.

If you spend most of your time inside Excel, Microsoft Copilot is worth considering because it fits directly into the Excel workflow.

For Google Sheets users, Gemini is the natural option to explore.

For more specialized data analysis, Julius AI can be useful. And if your work involves long documents, Claude and NotebookLM are particularly interesting.

The main lesson is simple: don’t choose an AI tool just because it has the longest list of features.

Choose the tool that works with the files you already use and the tasks you actually need to complete.

AI should remove repetitive work and help you understand information faster. It should not remove the need to check important results.
