About NekoSheet

Free browser spreadsheet

Open XLSX, CSV, TSV and TXT files to edit tables and perform basic calculations. No account or installation is needed.

Open, edit and save

Choose a file or drop it onto the page, then edit cells. Use SUM, AVERAGE, IF, borders, text colors and merged cells. Choose the file format and encoding when saving.

Your files stay with you

File contents are processed in your browser and never sent to a server. Detection of UTF-8, Shift_JIS and other encodings is an estimate. Check the import preview for garbled text.

Supported features

This is not a fully compatible replacement for Excel. Macros, charts, pivot tables and conditional formatting are not supported or preserved on export. Keep originals of important files.
