ZeninData

ZeninData independently hosts GridCraft v0.7.0, the manual browser spreadsheet editor developed by the ArtCraft team and contributors. We maintain the hosting site and English task guides; we did not create the upstream engine and are not an official ArtCraft release. Open local XLSX or CSV files in a desktop browser without an account, inspect and manually edit cells, use formulas and charts, and use the download controls. The natural-language AI agent is still in development and is unavailable. The hosted editor is a free alpha. For analysts checking a small handoff, the guides cover opening XLSX files, CSV-to-XLSX workflows and the limits compared with Excel. Keep the original and verify identifiers, calculations and saved results. A synthetic CSV test displayed 00107 as 107; a separate synthetic XLSX formula test recalculated SUM from 30.75 to 32.75 after editing an input. These observations do not establish export/reopen fidelity. VBA and full Power Query are unsupported. Workbook processing is local; the site includes GA4 usage analytics. This listing was prepared with AI assistance and checked against the live host and test evidence. Please decline if an independently maintained host with guides does not fit the directory.
