Why convert XLS to MD?
- The output can be tested in the destination workflow before the original is archived.
- A separate copy makes it easier to compare the old and new behavior.
- Conversion is useful when the destination has a strict format requirement.
- A converted copy keeps the original file intact for comparison and future edits.
Will quality change?
The document is rebuilt in Markdown, so layout fidelity depends on fonts, tables, columns, and complex objects. The original source remains the best reference for comparison.
Processing and limits
- Processing
- Server-side
- Engine
- LibreOffice and document tooling
- Maximum size
- 100 MB per file on the server.
- Batch support
- Yes, multiple files can be queued; completed results can be downloaded as a ZIP.
- Quality controls
- No quality slider. The output follows the fixed conversion path.
The file is processed on the server because the conversion requires a server-side engine or a utility operation.
- Excel features without a direct Markdown equivalent may not survive the conversion.
- The output is re-encoded, so keep the original source as the archive copy.
- Browser-first paths depend on local codec support; unsupported cases fall back to the server.
Platform compatibility
The output is a Markdown file. Use an application or device that accepts that format, and test the result on the destination platform if compatibility is critical.
When not to convert
- Skip the conversion when the destination already accepts Excel and no compatibility problem exists.
- For a one-off preview, a local viewer may be faster than creating a new delivery file.
- If Markdown support is uncertain on the destination device, test a sample before processing a large batch.
