CSV to SQL Converter
Turn CSV data into SQL INSERT statements with auto-quoting and NULL handling.
Turn CSV into SQL INSERT statements
The CSV to SQL Converter transforms a block of CSV data into ready-to-run SQL INSERT statements. Provide a table name, paste your CSV with a header row, and the tool generates one INSERT per row — automatically quoting text, leaving numbers unquoted, and turning empty cells into NULL. It all happens in your browser, so your data stays private.
Why convert CSV to SQL?
Data often arrives as CSV — exported from spreadsheets, reports, or other systems — but you need it in a database. Hand-writing INSERT statements for dozens or hundreds of rows is slow and error-prone. This converter bridges the gap in seconds, producing clean, correctly escaped SQL you can paste straight into your database client or migration script.
How to use it
- Enter the target table name.
- Paste your CSV, with column names in the first row.
- Copy the generated INSERT statements.
How values are handled
| CSV value | SQL output |
|---|---|
| Alice | 'Alice' |
| 30 | 30 (unquoted number) |
| (empty) | NULL |
| O'Brien | 'O''Brien' (escaped quote) |
Safe escaping
The converter escapes single quotes by doubling them (''), the standard SQL way, so text containing apostrophes won't break your statements. Quoted CSV fields are parsed correctly, including commas and quotes inside them. Numbers are detected and left unquoted so they insert into numeric columns cleanly.
Tips
- Make sure the header row exactly matches your table's column names.
- Review data types — if a numeric-looking value should be text, quote it in your CSV.
- For very large files, run the statements in batches to avoid timeouts.
Private and free
Your CSV is converted entirely in your browser — nothing is uploaded or stored. The tool is completely free with no limits.
Frequently asked questions
Does the first row need to be headers?
Yes. The first CSV row is used as the column names for the INSERT statements.
How are quotes and numbers handled?
Single quotes are escaped by doubling them, numbers are left unquoted, and empty cells become NULL.
Does it handle commas inside quoted fields?
Yes. The CSV parser respects quoted fields, so commas and quotes inside them are handled correctly.
Is my data private?
Yes. Conversion runs entirely in your browser and nothing is uploaded.
