CSV and JSON conversion FAQ
The tool analyzes the first line and picks the most frequent separator: a comma (,), a semicolon (;) used by Excel in many European locales, or a tab (\t) when you paste from a spreadsheet. Quoted fields, including ones with line breaks inside, are parsed correctly. Downloaded CSV files are saved as UTF-8 with a BOM so Excel displays non-Latin characters correctly.
