Turn plain English into Excel formulas

Describe what you want to calculate and get the exact Excel or Google Sheets formula, with a short explanation of how it works.

For the best results: Describe the calculation and name your columns or ranges (e.g. "sum column D where column B is 'paid'"). Say whether it is Excel or Google Sheets, a few functions differ. Paste a couple of sample rows for a more exact formula.

What is Excel Formula Generator?

Excel Formula Generator is a free AI coding assistant that turns a plain-English description of what you want to calculate into the exact Excel or Google Sheets formula, with a short explanation. Each request is handed to a code-specialized model chosen for the task, returning working code, bug fixes, and explanations in any programming language in seconds. You paste and go, with no login and nothing to install, and the code you share is not retained once the session ends.

✦Paste code and go, no login, nothing to install
✦Code-specialized models are selected per request automatically
✦Your code is not retained after the session ends

Models: It routes across strong coding models including Llama, Gemini and Mistral families, picking the best available one per request. The exact model used is shown after every response.

See it in action

A shop owner wants to total sales for one region in the current month straight from their sheet.

What you type

In my sales sheet, column B is the region, column C is the order date and column D is the amount. Total column D for rows where the region is 'South West' and the date is in this month.

What you get

Formula: =SUMIFS(D:D, B:B, "South West", C:C, ">="&EOMONTH(TODAY(),-1)+1, C:C, "<="&EOMONTH(TODAY(),0)) How it works: SUMIFS totals column D wherever column B equals "South West" and the date in column C falls between the first and last day of the current month. Google Sheets note: this formula works unchanged in Sheets.

Tip: If the answer reaches for a newer function like XLOOKUP or FILTER, it tells you which versions support it and offers a classic INDEX/MATCH fallback. Ask for the fallback outright if you're on an older Excel or sharing the workbook with colleagues who might be.

Use cases

What people use it for

Work out a SUMIFS formula to total sales for one region and month.

Fix a VLOOKUP that keeps returning N/A errors across two mismatched sheets.

Build a nested IF that sorts exam scores into grade bands without hunting for syntax.

Who uses Excel Formula Generator?

Finance analysts

building conditional totals and lookups across large workbooks without pausing to look up rarely used function syntax

Small business owners

turning a plain question about their sales sheet into a working formula they can paste and trust

Spreadsheet learners

learning how a formula is built and why it works, not just copying an answer into an assignment

How it works

1Paste your code or describe what you need built.
2A code-specialized model writes, fixes, or explains it.
3Copy the code out, or ask follow-ups to iterate on it.

Tips for the best results

Say whether you are in Excel or Google Sheets, since a handful of functions and array rules differ between them.
Give your real column letters or header names so the formula drops in without you rewriting every range.
Spell out the conditions in full, such as only rows where status is paid and the date is this month.
Test any complex formula on a copy of your data before letting it feed an important report.
Ask for the short explanation as well as the formula, so you can adjust it yourself when the data changes.

FAQ

Frequently asked questions

Does it write formulas for both Excel and Google Sheets?

Yes. Describe the calculation and say which one you use, since a few functions differ between them. Excel and Google Sheets share most functions like SUMIF, INDEX and MATCH, but things like array handling and some newer functions vary. Naming your app up front means the formula pastes in and works first time.

Does it fill in my spreadsheet or just give the formula?

It gives you the formula plus a short explanation of how it works, not a completed spreadsheet. You copy the formula into your own cell and adjust the ranges to match your data. This keeps your real numbers private and means you can reuse the same pattern anywhere it fits.

Can it explain a formula I already have?

Yes. Paste an existing formula and it breaks down each part in plain English, so you understand what a nested INDEX and MATCH or a long IF chain actually does. This is handy for an inherited spreadsheet you are afraid to touch, or before you edit a formula someone else built.

What details should I include for the best formula?

Say what you want to calculate, which columns or cells hold the data, and any conditions that apply. Mentioning your actual column letters or a header name helps, as does noting whether ranges might grow. The more precise the description, the less you have to adjust the ranges afterwards.

Can it handle advanced things like array formulas or pivot alternatives?

Yes. It can build array formulas, lookups across multiple criteria, dynamic ranges, and formula-based summaries that do a pivot table's job. Describe the result you want in words and it returns the formula with notes on where each part goes. Complex outputs are worth testing on a copy of your data first.

Is there a free Excel formula generator with no sign up?

Yes, this is one. Describe the calculation in plain English and get the formula with an explanation, free, with no account or payment. There is no cap on how many formulas you request, so bookmark it for the next time a spreadsheet stumps you.

Is the formula it gives me safe to use at work?

Yes. It returns a standard spreadsheet formula that runs entirely inside your own file, with nothing sent anywhere or installed. Since it works from your plain description rather than your data, no confidential numbers leave your machine. Always test the result on a copy before trusting an important report.

Why is my formula returning a REF or N/A error?

Usually a range was deleted, a lookup value has no match, or a column reference shifted. Paste the formula and describe what you expected, and it points out the likely cause and a corrected version. Checking for stray spaces and mismatched data types often clears these errors too.

What are the usage limits?

Code tools are text tools, so they are unmetered during the current free launch phase, iterate on a bug or generate as many drafts as the work needs. A short per-minute limit guards against scripted abuse only. Paid plans with higher limits and priority model access are coming soon.
