- Formula-like fields get a leading apostrophe. Record separators are written as CRLF.
- Embedded tabs require quoted TSV fields.
The input dialect accepts quoted tabs and line breaks, with doubled double quotes for a literal quote. CSV output uses commas and quotes fields as needed. Empty field positions are retained. Spreadsheet safety can add a leading apostrophe to formula-like values, which remains part of the downloaded text.
Maximum input size is 2 MiB per file.
