How XLSM turns into EXCEL: workbook object-model rebuilding
Cells, sheets, formulas, types, and print settings are read from XLSM and mapped into structures EXCEL can express. A displayed total is not enough evidence; formulas and leading zeros may have changed underneath it. XLSM unpacking inventories worksheets, formulas, links, styles, names, charts, pivots, controls, VBA, and signatures before recalculation or export. An Excel-labeled result promises workbook-style cells and sheets but still requires the concrete file generation, formula dialect, recalculation, and macro behavior to be verified.
Read as an OOXML Excel workbook containing cells and formulas plus VBA macros and possibly signed automation. Rebuilt as a generic spreadsheet destination for cells, tables, formulas, and worksheet data.

Acceptance evidence for the converted EXCEL
Record the XLSM evidence before conversion
Check macros and signatures, recalculate formulas, and inspect links, names, dates, pivots, charts, controls, and sheets.
Test the EXCEL file in its receiving workflow
Open the result in the required spreadsheet app and recalculate formulas before relying on totals.
Reading XLSM correctly and satisfying what EXCEL expects
What can fail when XLSM spreadsheet format is interpreted
Macro-free outputs remove VBA, while recalculation, external links, controls, and signatures may change independently of visible cells.
What Microsoft Excel workbook cannot safely promise
A generic Excel route may not preserve every workbook feature or choose the version a legacy system expects.
How the EXCEL writer handles this route
a generic spreadsheet destination for cells, tables, formulas, and worksheet data is what gets written, labeled as application/vnd.openxmlformats-officedocument.spreadsheetml.sheet. Whether that actually opens depends on the receiving application, not on the file extension.
When to actually choose XLSM to EXCEL
EXCEL earns its place when its editing, reflow, or reader support outweighs exact XLSM structure - Just test the most complex page or chapter before committing to it.
What changes between the XLSM model and the EXCEL deliverable
- The source stores an OOXML Excel workbook containing cells and formulas plus VBA macros and possibly signed automation; the destination stores a generic spreadsheet destination for cells, tables, formulas, and worksheet data. Compare application metadata after that structural change.
- Metadata handling differs between XLSM and EXCEL; do not assume every application-specific field carries across untouched.
