Multi-format Table Converter
Multi-format Table Converter is a free online tool for converting between Markdown tables, CSV, Excel, and HTML tables. Upload a file, paste source code, or copy cells directly from Excel.
Parsing and conversion happen entirely in your browser, so table data is never uploaded. Copy the result or download it as .md, .csv, .xlsx, or .html.
How to Use
- Choose the source format on the left, then upload a file or paste table content
- If the source contains multiple tables, select the sheet or table to convert
- Choose the target format on the right and set whether the first row is a header
- The result updates automatically; copy it or download it locally
FAQ
Which table formats are supported?
Markdown tables, CSV, Excel (.xlsx/.xls), and HTML tables can all be converted between one another.
Are table files uploaded to a server?
No. Files are read, parsed, and converted locally in your browser, so the data never leaves your device.
How are Excel files with multiple sheets handled?
All worksheets are listed after upload, and you can select one to convert. Multiple HTML or Markdown tables can be selected the same way.
Are Excel formulas and styles preserved?
No. The converter uses displayed cell values and does not preserve formulas or styling, which keeps data exchange consistent across text formats.
