Does it handle commas inside quoted fields?

Yes. CSV quoting follows RFC 4180, so commas, double quotes, and line breaks inside a cell are preserved.

Can it read semicolon-separated files?

Yes. The delimiter is detected from the first rows, and the app tells you when it chose something other than a comma.

How many rows can I convert?

Guests can process up to 500 rows per file. A free account raises that to 50,000 rows, still entirely in your browser.

Are empty cells written as NULL?

Empty cells and the text NULL (case-insensitive) become NULL. Other placeholders like NA or - are kept as text.

CSV to SQL INSERT statements

Drop a CSV and get INSERT statements back. The parser tolerates the messy files people actually have: semicolon and tab separators are auto-detected, unclosed quotes are reported with a line number, and GBK-encoded exports from Chinese Excel open without garbled text.

Every value is escaped for the dialect you pick, so a name like O'Connor becomes 'O''Connor' in the SQL instead of breaking the statement.

SQL INSERT

Drop a file to generate INSERT statements

Processing stays in this browser. Guests can process up to 500 rows per file.
