A new take on the workflow.

tuisheet documents a keyboard-driven spreadsheet workflow with editable cells, multiple worksheets, formula calculation, undo and XLSX file handling. Its maker describes the project as mostly vibe coded with Codex and OpenCode, and says it replaced Excel and LibreOffice for daily personal spreadsheet work. Released binaries are available.

What you can switch today.

Replace Excel for local cell-based tables and ordinary formula calculations in XLSX workbooks using a terminal interface.

Download a platform release and open a copy of a simple XLSX workbook.
Edit cells and worksheets and check the specific formulas your work uses.
Save a copy and compare values and formatting in the existing spreadsheet reader before moving further files.

Switching caveat. Suitable for the documented cell/formula workflow; advanced Excel automation and complex workbook fidelity are not established. Workflow evidence

Where it falls short.

Terminal interface rather than Excel ribbon. Linux is the maker’s best-tested platform; Windows has shortcut differences. Only the documented formula set is established. Charts, VBA, Power Query and fidelity of complex workbooks are not established. Source-documented capabilities have not been independently runtime-tested.

Maker claims AI build. The original first-party README explicitly says the spreadsheet was mostly vibe coded using Codex and OpenCode with several models, with manual cleanup. The maker also reports using it daily instead of Excel; this personal report is not an independent compatibility test. Inspect the evidence

A formula checklist does not establish workbook compatibility. Check recalculation, macros, pivots and external connections on representative files.
