About
ZeninData is an independent host of GridCraft v0.7.0, the open-source web spreadsheet editor developed by the ArtCraft team and contributors. We maintain the hosting site and English workflow guides; we did not build the upstream editor engine.
Open a local XLSX or CSV file in a desktop browser, edit cells manually, work with formulas and charts, and download a copy. There is no account or workbook-upload requirement. The guides cover opening XLSX, CSV-to-XLSX handoffs and Excel compatibility.
The current editor is free and alpha. Keep originals, check important identifiers and calculations, and save before leaving. In one synthetic CSV import test, the input identifier 00107 appeared as 107 in both the grid and formula bar. Exported bytes were not verified in that test. Complex Excel features may not survive; VBA and full Power Query are unsupported.
The planned natural-language AI agent is not available. Website usage is measured with GA4. This listing was prepared with AI assistance and checked against the current host and test evidence.
