Question 1

What kinds of SQL can this converter handle?

Accepted Answer

It parses INSERT INTO statements (with or without an explicit column list) and bare value tuples, then outputs RFC 4180-compliant CSV. NULL becomes an empty field, numbers stay unquoted, and strings containing commas, quotes or newlines are automatically quoted and escaped.

Question 2

How are SQL NULL and booleans written in the CSV?

Accepted Answer

By default SQL NULL becomes an empty CSV cell. You can optionally render it as the literal word NULL. Booleans true/false are written as the words true and false. Numbers keep their original form. All other values are treated as strings and quoted only when necessary.

Question 3

Does it support multiple INSERT statements at once?

Accepted Answer

Yes. Paste several INSERT statements separated by semicolons. The converter merges all rows into one CSV. If the column lists differ between statements, the union of all columns is used as the header and missing cells are left empty.

Question 4

Is my SQL data sent to a server?

Accepted Answer

No. All parsing and conversion happens entirely in your browser using JavaScript. Nothing is uploaded, stored or transmitted. The tool works offline after the page loads.
