operating models, reports, and data workbooks
XLSX operations
Native Excel operations, one result contract.
Operate on operating models, reports, and data workbooks while keeping workbook formulas and sheet structure, typed failure, declared losses, and artifact evidence explicit.
Workbook formulas and sheet structureRegistered surface
7 stable XLSX operations.
The registry—not this page—defines the executable contract and current stability.
xlsx.convertExport a workbook to the requested target form.
stablexlsx.inspectEstimate the cost and shape of a render without producing the workbook.
stablexlsx.parseRead workbook bytes into the structured model.
stablexlsx.renderRender a structured document to a native Excel (.xlsx) workbook.
stablexlsx.repairRepair defects in workbook bytes, reporting every change as a loss.
stablexlsx.transformApply a mapping to a workbook and return the result.
stablexlsx.validateLint a spreadsheet document, or inspect workbook bytes, without modifying either.
stablePreserve what the format owns.
Workbook formulas and sheet structure remains a format-specific concern. Runstamp does not flatten it into a universal document model and call the result equivalent.
Make compromise observable.
When an operation cannot preserve a feature, its descriptor and result determine whether to collect the loss or fail the run.
