Free online spreadsheets with every formula
SheetsBat is a spreadsheet app that runs in any browser. It calculates 536 functions, from SUM and SUMIFS to XLOOKUP, FILTER, LET, LAMBDA, GROUPBY and PIVOTBY, with dynamic arrays that spill into the cells next to them. Function names, arguments and error values work the way spreadsheet people expect, so the formulas you know work the first time.
Your Excel files open just as they are, with their formulas, formatting, tables and rules, and download again as .xlsx, .ods, CSV or PDF. Add charts that follow your data, summarise thousands of rows with a pivot table and slicers, and let conditional formatting point out what needs attention.
AI that writes and explains formulas
Describe what you need in plain words and SheetsBat AI writes the formula with your real headers and ranges. It can also fill a column, answer questions about your data, explain a formula someone else wrote and fix errors. You see every change before it goes in, and Undo removes it.
