FAQ

Is my data sent to a server?

No. All processing happens in your browser.

Does it support quoted fields in CSV?

Yes. Basic RFC 4180 quoting is supported, including commas inside quoted fields and escaped double quotes.

What happens if rows have different column counts?

Rows are padded with empty cells to match the maximum column count.

Can I set column alignment in the Markdown table?

Currently all columns output with default alignment (---). For specific alignment, manually edit the output after conversion.

Can it handle large amounts of data?

Subject to browser memory, hundreds of rows process fine. For very large CSV files, consider using a script-based tool.
