QUICK ANSWER
Convert the workbook content without running its automation
XLSM is Excel’s macro-enabled XML workbook format. It preserves the worksheet and chart features associated with XLSX while allowing VBA projects and Excel 4.0 macro sheets.
The converter reads static workbook content and ignores executable behavior. Rows, columns, sheet values, and table-like areas become Markdown; macros, event handlers, and user forms do not run or migrate.

FORMAT-SPECIFIC NOTES
XLSM separates visible workbook data from executable macro logic
A macro can populate cells, refresh external data, build reports, or react when a workbook opens. A static parser sees only content saved in the file; it does not reproduce runtime changes that have not been stored.
This makes local conversion useful for safe inspection and archival, but not a replacement for testing a trusted automation workflow in Excel.
CONVERSION DETAILS
What transfers to Markdown—and what does not
What AnyDoc preserves
Saved worksheet state
Cell text, numbers, cached values, and rectangular data regions are serialized from the saved workbook.
Sheet organization
Workbook sheets remain distinguishable instead of being concatenated as an unlabeled data stream.
Static formula information
Stored formulas or cached results can appear as readable content where exposed by the parser.
What Markdown simplifies
Macro behavior
VBA modules, XLM macro sheets, buttons, forms, and event-driven updates are not executed or converted.
External refreshes
Power Query, external connections, and linked workbooks are not refreshed in the browser.
Spreadsheet presentation
Charts, conditional formatting, number-format nuances, and interactive controls are flattened.
PRACTICAL USES
When XLSM to Markdown is useful
Security-conscious review
Inspect the data in an unfamiliar XLSM without enabling workbook macros.
Operational archive
Preserve report output separately from the VBA automation that originally produced it.
AI data preparation
Extract the saved tabular state for permitted analysis without uploading a macro-enabled source file.
HOW TO CONVERT
A workflow designed for XLSM files
- 01
Do not enable macros
Upload the saved XLSM directly; conversion requires no Excel security prompt.
- 02
Identify generated ranges
Check whether a macro normally fills blank cells or refreshes data before reports are complete.
- 03
Archive both layers
Keep the original XLSM for code and automation, and use Markdown as the static readable record.
FREQUENTLY ASKED
XLSM to Markdown questions
Does XLSM to Markdown execute VBA?
No. Neither VBA nor Excel 4.0 macro sheets run in the WebAssembly converter.
Are macro-generated values preserved?
Only if those values were saved into worksheet cells. Unsaved runtime output cannot be reconstructed without running the macro.
Can I convert XLSM by renaming it XLSX?
No. The package content types still identify a macro-enabled workbook. Renaming can make Office reject the file.
Are formulas recalculated?
No. Markdown is static, so the output uses information saved in the workbook rather than running Excel’s calculation engine.
