The list
Slaide
Our pickBest for: Creating a live, working spreadsheet from your data, free to start with no card.
Builds a live spreadsheet with working formulas from your own data, paste numbers, upload an Excel file or describe what you need, and get a structured sheet you can click into and edit. It's a strong fit for creating a clean, working spreadsheet quickly; for heavy analysis and advanced functions, Excel with Copilot below is more powerful.
Not ideal for: Heavy analysis, large datasets and advanced Excel functions; Excel with Copilot is more powerful there.
Microsoft Copilot in Excel
Best for: Heavy, formula-intensive analysis for people already in Excel.
Microsoft's AI inside Excel itself: it writes and explains formulas, analyses data and surfaces insights with the full depth of Excel behind it. It is a strong option for serious, formula-heavy spreadsheet work; current consumer M365 plans include Copilot features, while Business and Enterprise capabilities depend on the organisation's licence.
Not ideal for: Anyone outside Microsoft 365, or a quick sheet you want built for you without working in Excel yourself.
Google Sheets with Gemini
Best for: Workspace users who want AI building and editing inside Google Sheets.
Gemini in Google Sheets can build and edit spreadsheets from plain-language requests and adds an =AI() function for in-cell generation, all inside Sheets. A natural choice for Google Workspace users; it's available on consumer AI plans and paid Workspace tiers.
Not ideal for: Teams that work in Excel files and need .xlsx as the finished format.
Equals
Best for: Finance and revenue teams that need connected, always-current reporting.
A browser-based spreadsheet built for analytics and reporting, with live data connections and AI for building models and dashboards, aimed at finance and revenue teams. It leads for connected, always-current reporting; it's a paid, team-oriented platform rather than a free general tool.
Not ideal for: An individual who needs one free, general-purpose spreadsheet; it is a paid, team-oriented platform.
ChatGPT
Best for: Exploring a dataset and asking questions about it in plain language.
Analyses uploaded .xls, .xlsx and .csv files in a chat: it summarises rows, trends and outliers, runs calculations in Python and creates tables and charts, according to OpenAI's help page on data analysis. Strong for understanding a dataset or answering questions about it; for a workbook with live formulas that you keep editing, a spreadsheet tool is the better home.
Not ideal for: A workbook with live formulas you keep maintaining; the analysis happens in the chat.
Claude
Best for: A first working model or analysis as a downloadable .xlsx file, straight from a chat.
Creates Excel (.xlsx) files from a chat, including financial models with working formulas, and analyses uploaded data, according to Anthropic's help page on file creation. File creation is available on all Claude plans, the free one included. A good way to get a first working model; you review the formulas and the layout yourself.
Not ideal for: A polished, branded workbook out of the box, or live data connections.
Julius AI
Best for: Exploring and charting a dataset before you build the final sheet.
Analyses spreadsheets and data files in a chat, producing charts and written findings from your numbers. Strong when the hard part is the analysis itself rather than the workbook.
Not ideal for: A formula-driven workbook you keep editing in Excel; it is built around chat analysis of your data.
