questions
Answers before you convert.
Does each Excel sheet become a separate section?+
Yes. Worksheets are labeled with their sheet names and converted into Markdown tables.
Are formulas preserved?+
Formula information is retained as a note beside a value when the workbook contains both a formula and a cached result. A formula without a cached value is represented as an equals expression.
Can I convert XLS files?+
The legacy binary .xls format is not supported in the browser. Save or export the workbook as XLSX, then convert that file.
