ZeninData independently hosts GridCraft v0.7.0, the open-source spreadsheet editor developed by the ArtCraft team and contributors. We maintain this hosted entry point and practical English guides, not the upstream editor engine.

For developers or analysts inspecting a small local export, the current workflow is to open an XLSX or CSV file without an account, inspect and edit cells with manual controls, add formulas or charts, and download an XLSX workbook or export the active sheet as CSV. Our guide explains checks for dates, identifiers and CSV-to-XLSX conversion: https://zenindata.ai/guides/csv-to-xlsx/

The editor is alpha software. Keep original files and verify a downloaded copy before relying on it; VBA macros and a full Excel Power Query workflow are not supported. There is no shared cloud workbook service here. The planned natural-language AI agent is not integrated or available.
