How the json to sql insert converter works
The tool parses your JSON (an array of objects, or a single object) and builds INSERT statements. The column list is the union of the objects’ keys in first-seen order, and each value is typed and escaped: numbers and booleans become SQL literals (TRUE/FALSE), null and missing keys become NULL, and strings are wrapped in single quotes with embedded quotes doubled (O'Brien → 'O''Brien'). By default it emits one compact multi-row INSERT; tick the option for a separate statement per row.
The single-quote escaping matters: it’s the difference between a clean import and a broken statement (or an injection risk) when your data contains apostrophes. Column and table names are lightly sanitised to safe identifiers. This generates standard ANSI-style INSERTs that work in PostgreSQL, MySQL and SQLite; if your dialect needs backtick-quoted identifiers or a different boolean literal, a quick find-replace adjusts it. Everything runs locally, so the data you paste never leaves your browser.
Frequently asked questions
How do I convert JSON to SQL INSERT statements?
Paste a JSON array of objects, set the table name, and the tool outputs INSERT statements with the keys as columns and each object as a row. Copy and run them in your database.
How are values escaped?
Numbers and booleans become SQL literals, null becomes NULL, and strings are single-quoted with any embedded apostrophe doubled (written as two single quotes), so apostrophes in your data can’t break the statement.
Can I get one statement per row?
Yes, by default it produces a single multi-row INSERT (efficient for bulk loads); tick the option to emit a separate INSERT statement for each row instead.
Which SQL databases does it work with?
It produces standard INSERT syntax that runs in PostgreSQL, MySQL and SQLite. For dialect-specific identifier quoting you may tweak the output, but the values and structure are portable.
Is my data uploaded?
No, the conversion runs entirely in your browser and works offline, so your data stays on your device.
