Plain English to the exact spreadsheet formula.
Describe what you need. Cellsmith writes the Google Sheets or Excel formula — copy-ready, with a one-line explanation so you actually understand it. Does regex and SQL too.
One tool, three things people in spreadsheets need constantly
SUMIF, VLOOKUP, INDEX/MATCH, nested IFs, XLOOKUP, ARRAYFORMULA — easy to forget, easy to get subtly wrong. Describe the result; Cellsmith writes it and explains it so you can trust it and tweak it.
Spreadsheet formula generator
"Sum column C where column A says Paid", "count rows over 500" — get the exact Google Sheets or Excel formula, with a plain-English read-out.
Regex builder
"Match a US phone number", "extract the domain from an email" — get a working pattern plus an explanation of every part.
SQL snippet writer
"Orders per day for the last 7 days" — get clean, readable SQL you can sanity-check and run.
Does it work for both Excel and Google Sheets?
Yes. Cellsmith writes formulas that work across Google Sheets and Excel, accounting for the differences — argument separators, function availability like XLOOKUP vs. ARRAYFORMULA, and locale behavior.
Will I understand the formula it gives me?
That's the point. Every result ships with a short plain-English explanation so you can verify the logic and adapt the cell ranges to your own sheet.
Is my data sent anywhere?
You only describe what you want — you never paste your data. Your request is sent to a metered proxy that keeps the AI key server-side; if it's ever unavailable, the page falls back to an offline sample so it still works.
