Google Sheets add-on
PromptCell gives spreadsheet teams AI formulas that are built around real work: standardize messy data, pull results from another sheet, classify leads, and draft follow-ups directly where the work already lives.
Lead with outcomes, not formula trivia. PromptCell is strongest when you ask it to finish a spreadsheet task that would normally take repetitive formulas or manual cleanup.
Normalize casing, fix abbreviations, trim whitespace, rewrite inconsistent values, and keep the same row and column shape when you need a clean replacement range.
=ASKR("Trim spaces and standardize state abbreviations", A2:D10)Use a search key from one range, match it against another sheet, and return the aligned result without building a complicated XLOOKUP stack.
=ASKX("Return the matching customer tier", A2, Customers!A:A, Customers!C:C)Turn long rows into short summaries, lead scores, next-step notes, or plain-language explanations for the rest of the team.
=ASK("Summarize this customer row for the sales team", A2:F2)Filter rows, extract fields, create headers, or return a fresh structured output when the result should not match the original shape.
=ASKT("Return only active deals with owner and next step", A2:H200)Most teams are live in a few minutes.
Install the add-on from Google Workspace Marketplace, then open any spreadsheet where you want AI help.
Use Google sign-in inside the PromptCell sidebar. New sheets can reuse the same saved account automatically.
Start with a simple task like summarizing a row, cleaning a range, or matching a customer tier from another sheet.
Move into paid billing only when the team is ready. Gemini uses 1 usage unit. Claude uses 3 usage units.
The formulas are designed around single-cell answers, same-shape rewrites, flexible tables, and cross-sheet lookup tasks.
Provider keys remain under your control instead of being pasted into shared spreadsheets.
Gemini and Claude are weighted differently, so billing stays closer to actual provider usage.
