Excel to Markdown Output
The goal is readable Markdown tables and sheet structure, not a fully interactive spreadsheet.
Markdown tables
Compact worksheets can become Markdown tables that are easier to paste into prompts and docs.
Worksheet sections
Multiple sheets may appear as separate Markdown sections where the workbook exposes them cleanly.
Rows and labels
Headers, rows, and simple labels are kept when they can be represented clearly in Markdown.
Formula values
Formula behavior is not preserved as executable spreadsheet logic; review important calculations.
Excel to Markdown Limits
Spreadsheets can contain formulas, merged cells, charts, images, and very wide tables. The Markdown result may need cleanup.
Limit
XLSX is the supported Excel input. Legacy .xls should be saved as .xlsx first.
Limit
Very large worksheets, merged cells, formulas, charts, and embedded images may not convert into clean Markdown.
Limit
Formula results may appear as values, but spreadsheet formulas are not preserved as executable logic.
