Nixt Sheets documentation

Nixt Sheets opens, edits and saves Excel workbooks (.xlsx). It also opens .xlsm, .xltx and .xltm workbooks and delimited text (.csv and .tsv). It works on the file on your computer: you don’t need an account to open a file, nothing is synced, and the app sends no telemetry.

What Nixt Sheets is for

Nixt Sheets is built for spreadsheets and opens nothing else. If you try to open a Word document, a presentation or a PDF, it tells you which Nixt Office app opens that file instead — Nixt Writer, Nixt Slides or Nixt PDF.

It is designed around one idea: a workbook you open should still be the same Excel file when you save it. Parts of the file that Nixt Sheets doesn’t use — a macro project, an embedded font, custom XML — are written back unchanged. Formulas give the same answers Excel gives, including Excel’s own quirks. File formats and compatibility explains what that covers.

Where to start

Getting started — create, open, save and close a workbook.
The workbook window — what each part of the window is for, and a map of every ribbon tab.
Entering and editing data — typing, filling and pasting.
Writing formulas — references, names, errors and recalculation.
Keyboard shortcuts — the keys that work in the grid.
