Sum revenue in column D where region is West and status is Paid
=SUMIFS(D:D, B:B, "West", C:C, "Paid") Adds every Paid order from the West region.
My VLOOKUP returns #N/A, but the value is right there
=XLOOKUP(TRIM(E2), A:A, C:C, "Not found") The lookup column had trailing spaces, and TRIM clears them.
What does =INDEX(C:C, MATCH(E2, A:A, 0)) actually do?
It finds the value from E2 inside column A, then returns the value on that same row from column C. A flexible two-way lookup.

Acme, Globex, Initech, Umbrella, and Soylent: your top five by Q3 spend.

FAQ
Questions, answered
Everything about accuracy, billing, and the spreadsheets we support.
What can ExcelPerfect do?
It is an AI copilot for spreadsheets. Describe what you want and it writes the exact Excel or Google Sheets formula, fixes broken formulas and errors, explains confusing formulas in plain English, and chats with your own data. It can also build new sheets, columns, charts, and formatting, then hand you a finished file. On top of that it writes VBA macros, regex, and SQL.
How accurate are the formulas?
ExcelPerfect is tuned for spreadsheet syntax and explains every result, so you can verify the logic before you paste. When you attach a file it runs its checks against your real data, and it writes formulas in your region’s syntax. Debug mode finds and fixes errors like #REF!, #VALUE!, and #N/A.
Can it work with my own spreadsheet?
Yes. Upload an .xlsx, .xls, or .csv (up to 5 MB) and it reads your real rows, formulas included, to answer questions and make edits. Ask it to add columns, charts, or formatting and download a corrected workbook. Your original file is never modified, because every edit lands in a fresh copy.
Does it work with Google Sheets too?
Yes. Pick your dialect, Excel or Google Sheets, and you get formulas written for that exact flavour, including Sheets-only functions like ARRAYFORMULA and QUERY.
Is my data private?
We process your messages and files only to answer your questions and make the edits you ask for. We never sell your data or use it to train advertising models. Uploaded files are stored temporarily so follow-ups and downloads work, then auto-deleted. You can export or delete everything from your account anytime.
How is usage measured?
In tokens, the standard unit of AI usage (roughly ¾ of a word, in and out). A quick formula uses a few thousand. A deep chat over an attached spreadsheet uses more. Free includes 50K a month, and Pro includes 6M.
How does billing work, and can I cancel?
Pro is $9/month through Stripe, monthly only, and you can cancel in one click anytime. Need more than the monthly allowance? Pro members can top up with one-time packs ($5 to $20) that never expire.
