Frequently asked questions
- What happens to rowspan and colspan in CSV or TSV?
- The value is repeated into every covered cell to create a rectangle, and a merged-cell warning is shown.
- Can CSV or TSV restore the original merged cells?
- No. Delimited formats do not contain merge metadata, so the reverse conversion creates a regular rectangular HTML table.
- Are HTML classes and link URLs preserved?
- No. This is a semantic conversion of displayed cell text and table structure.
