ZeninData - Showcase Project

About ZeninData
Open XLSX and CSV in a free browser spreadsheet, without an account.
ZeninData is an independent browser host of GridCraft v0.7.0, the open-source spreadsheet editor developed by the ArtCraft team and contributors. We maintain the hosting and English task guides, rather than the upstream spreadsheet engine. Open a local XLSX or CSV file without creating an account, use manual spreadsheet controls for formulas, formatting, sorting, filters and charts, then download your work. A sample sales workbook lets visitors explore the interface first. Workbooks are processed in the browser; ZeninData does not operate a workbook upload or cloud-save service. The current editor is free and in alpha. Keep original files, check complex Excel compatibility and important calculations, and download changes before closing the tab. VBA macros are not supported. The planned natural-language spreadsheet agent remains in development and is not available in the current release. This project is being shared for feedback on the browser workflow and starter guides. It is not offered for sale. ZeninData is not affiliated with ArtCraft or Microsoft. Website usage is measured with Google Analytics; workbook contents, cell values and filenames are not sent as custom analytics events.
