AI Excel (aiexcel.pro) is a free, no-sign-up web tool that converts plain-English descriptions into working Excel and Google Sheets formulas, explains formulas you paste in, and generates VBA macros and RE2 regex patterns.
What is AI Excel?
AI Excel is a browser-based spreadsheet assistant that takes a sentence describing what a cell should contain and returns a finished formula for Microsoft Excel (2016 through Microsoft 365) or Google Sheets, plus a line-by-line explanation of how that formula evaluates. Alongside the generator it ships three more tools: a formula explainer that reformats pasted formulas with the nesting visible and evaluates them from the inside out, a VBA code generator that returns a complete Sub with Option Explicit and qualified object references, and a regex generator that writes patterns for RE2, the engine behind Excel's REGEXEXTRACT and Google Sheets' REGEXMATCH. There is no account, no card and no download; prompts are sent to Cloudflare Workers AI to be answered, and nothing is stored.
What makes AI Excel stand out?
- No account barrier — typing a request into the box and pressing Generate is the entire workflow; there is no sign-up, card or expiring trial anywhere on the site.
- Daily free quota — every visitor gets 20 generations per day per IP address, resetting at midnight UTC, with no paid tier to upgrade into.
- Excel / Google Sheets dialect switch — the answer changes with the target, using ARRAYFORMULA and QUERY where those are the idiomatic Sheets answer and the correct argument separator for each platform.
- Version-aware output — the generator targets Excel 2016 and later and flags when a formula needs Microsoft 365 or 2021 for XLOOKUP, LET or the dynamic array family.
- Formula explainer — paste a formula you did not write and get it reformatted with nesting visible and evaluated from the inside out.
- VBA and macro generation — describe an automation and get a complete Sub with Option Explicit and every object reference qualified.
- RE2-targeted regex — patterns are written for the RE2 engine behind REGEXEXTRACT and REGEXMATCH, avoiding lookbehind constructs that would not run.
- Function reference library — 336 functions documented with real syntax, worked examples, the error codes each one actually produces, and a generator scoped to that function; grouped as Lookup and Reference (23), Logical (20), Text (35) and Web (3).
Who should use AI Excel?
- Analysts who inherit other people's spreadsheets: paste a 400-character formula showing #REF! into the explainer to see its nesting and evaluation order before attempting a fix.
- Excel and Google Sheets beginners who know the result but not the syntax: describe what a column should do and get nested IFs or an INDEX/MATCH written for the correct dialect.
- Operations and finance staff automating repetitive work: describe a routine and receive a VBA Sub with Option Explicit and qualified object references.
- Anyone working on data they would rather not upload: the tool receives only text, keeps no history and has no account, so there is no stored profile or dataset.
What can you do with AI Excel?
- Spreadsheet builders: turn "sum column F where column D is not cancelled" into a working formula with the right argument separator for your Excel or Sheets install.
- Debuggers: paste a formula you did not write and read its evaluation from the inside out, then check the named error modes on that function's reference page.
- Automation writers: convert a described macro into a complete VBA Sub, or write a REGEXEXTRACT pattern that runs on RE2 without lookbehind surprises.
- Function lookup: browse any of 336 documented functions for its real signature, three worked examples on one dataset, and the error codes it produces.
How does AI Excel work?
Pick the target dialect (Excel or Google Sheets), type a description of the formula you want, and press Generate; the tool returns the formula plus an explanation, and every answer ships with a "Watch out for" section naming what could break it. The site advises naming columns by both letter and header, stating every condition including negatives, giving the starting row, and confirming the argument separator matches your spreadsheet before generating rather than translating afterwards.
Pricing
AI Excel is free. There is no account, no card and no trial, and no paid tier exists. Every visitor gets 20 generations per day per IP address, resetting at midnight UTC; the cap exists because each AI call costs the operator money, not to push users toward a subscription.
FAQ
Is AI Excel free?
Yes. Every tool on the site runs without payment, a card or an expiring trial, and there is no upgrade path. The only limit is 20 generations per day per IP address, resetting at midnight UTC.
Do I need to sign up?
No. There is no sign-up anywhere on aiexcel.pro. You type your request into the box and press Generate; the site stores no account, no prompt history and no copy of what you typed.
Does it work with Google Sheets?
Yes. Each tool has an Excel / Google Sheets switch, and the answer changes accordingly — ARRAYFORMULA and QUERY appear where those are the idiomatic Sheets answers, and the argument separator matches the chosen dialect.
Which Excel versions are supported?
The generator targets Excel 2016 and later, and tells you when a formula requires Microsoft 365 or 2021 — for example XLOOKUP, LET or the dynamic array family, none of which exist in Excel 2019.
Is the output guaranteed correct?
No. Language models get spreadsheet syntax right most of the time and confidently wrong some of the time, so treat each answer as a strong first draft: test it against a row whose value you already know, check blank-cell behaviour, and confirm the range covers rows you will add later.
