What happens to your data
Kept
- The first row is used as the header and empty lines are skipped
- The separator is detected for you (comma, semicolon, tab or pipe), so exports from regional Excel versions work
- Quoted cells that contain separators, quotes or line breaks are read correctly
- Saved as UTF-8 with a BOM, with tabs between columns, so commas inside values need no quoting
- Values are copied as they are; only the separator changes
Good to know
- Values arrive as text and become numbers only where that is unambiguous and the target can hold numbers.
- Tabs and line breaks inside a value are wrapped in quotes automatically so the columns stay aligned.

CSV vs TSV
CSV
A CSV (Comma-Separated Values) file stores tabular data as plain text — each line is a row, commas separate the columns. It's the most universal way to move spreadsheet data between programs: Excel, Google Sheets, databases, and most apps can all read it.
Used in: Excel & Sheets exports · Database exports · Data sharing
TSV
A TSV (Tab-Separated Values) file is just like CSV, but it uses tabs instead of commas to separate columns. It's handy when the data itself contains commas — like addresses or descriptions — since tabs won't get confused with the content.
Used in: Spreadsheet exports · Data containing commas · Bioinformatics data
