Guides
Task-focused walkthroughs for common Ironsheet workbook workflows.
Each guide covers one part of the Ironsheet workbook engine in depth. Start with Safe writes if you have not already read Getting started — it covers the validation-gated flow every other guide builds on.
Safe writes
The recommended Node flow, the WorkbookSafeWriteReport shape, and changed-vs-repacked semantics.
Template rendering
Transactional template fills, explicit preflight, and starter templates.
Workbook API
API conventions, cell values, and the full stable method surface.
Styling
Fonts, fills, borders, alignment, and number formats without style explosion.
Rows and sheets
Structural row edits and the worksheet lifecycle.
Diffs
Semantic workbook diffs and package-level ZIP diffs.
Validation
Failure rules, semantic validation, and compatibility gates.
Browser usage
Editing workbooks with Blob, File, and ArrayBuffer in the browser.
