Proposed Group: AI-Editable HTML Workbook Community Group [via Community and Business Groups]

The AI-Editable HTML Workbook Community Group has been proposed by Ji Zhang:






Workbook-style HTML exports are often designed as visual renderings rather than editable document formats. As a result, automation tools and AI agents do not have a reliable way to identify the workbook model, make targeted edits, preserve formulas, styles, images, and metadata, and round-trip the result without rewriting unrelated runtime or presentation markup.

This Community Group will incubate a browser-openable HTML workbook profile with an explicit, editable workbook data region and related guidance for validation, AI-assisted editing, and interoperability.

The initial contribution is CWS HTML 1.0 Draft, where workbook data is plain JSON inside script#websheet-model, with explicit HTML markers, an AI editing guide, JSON Schema, validation tests, and optional per-image asset encoding. The work focuses on browser-openable, AI-editable workbook HTML files, not on replacing OOXML, ODF, CSVW, Microsoft Excel, Google Sheets, or browser-native spreadsheet editing. See the explainer for more background.

This group will discuss and refine recognition markers, the editable workbook JSON model, AI editing guidance, conformance requirements, security and privacy considerations, test suites, validators, examples, and implementation reports. This group may publish Specifications.

Note: The group will take inspiration from the CWS HTML 1.0 Draft, and that work may inform the group's discussions. That work does not constrain the group's discussions, and all decisions about the group's
deliverables will be made by the Community Group participants.






 You are invited to support the creation of this group.
 Once the group has a total of 5 supporters, it will be launched and people can join to begin work. In order to support the group, you will need a W3C account.




Once launched, the group will no longer be listed as "proposed"; it will be in the list of current groups.




 If you believe that there is an issue with this group that requires the attention of the W3C staff, please send us email on site-comments@w3.org




Thank you,
W3C Community Development Team
