What is SQL INSERT to JSON Converter?
The SQL INSERT to JSON Converter takes INSERT statements — the rows that seed a database — and turns them back into structured JSON or CSV. Paste a single statement or an entire dump with multiple tables; the parser infers each value type, flags malformed lines with line numbers, and lets you export the result as a JSON array, JSON grouped by table, or CSV.
Key Benefits
- Turn SQL seed data into JSON for API mocks and fixtures in seconds
- Automatic type inference — numbers stay numbers, NULL becomes null
- Handles multiple statements, tables, and escaped quotes in one paste
- Line-numbered warnings catch data problems before they hit production
- Fully client-side processing keeps sensitive dumps off the network
Common Use Cases
- •Converting database seed files into JSON fixtures for automated tests
- •Extracting sample rows from a production dump into a frontend mock API
- •Moving INSERT-based reference data into a spreadsheet via CSV export
- •Reviewing legacy SQL migrations by seeing the actual row data as JSON
- •Recovering data from SQL backups when only INSERT statements are available
How to Convert SQL INSERT Statements to JSON
- Paste your INSERTs: Drop one or more INSERT INTO statements into the input box — multi-row VALUES and multiple tables are fine — or press Load example.
- Pick a format: Choose JSON array, JSON objects grouped by table, or CSV from the format buttons; the output preview updates instantly.
- Check the summary and issues: The summary counts statements, rows, and issues, and any warning — like a column and value count mismatch — shows its line number so you can fix the SQL.
- Copy or download: Press Copy to take the JSON or CSV, or Download to save insert-data.json or insert-data.csv, then Clear to start a new batch.
Key Features
- Parse single or multi-row INSERT statements, with or without column lists
- Type inference: integers, decimals, booleans, NULL, and hex literals
- Three output formats: JSON array, JSON grouped by table, and CSV
- Handles escaped quotes (double-quote and backslash) inside string values
- Line-numbered issue list for unclosed parens, empty values, and column mismatches
- Works fully offline in the browser — no data is uploaded anywhere
Frequently Asked Questions
Which output formats are available?
Three — a JSON array with one entry per statement, JSON objects grouped by table name, or CSV. Switch with the format buttons, then copy or download the result as .json or .csv.
How are data types handled?
Values are typed automatically: unquoted numbers stay numbers, TRUE/FALSE become booleans, NULL becomes null, quoted strings stay strings (with both escape styles resolved), and 0x hex literals become numbers.
What if my SQL has problems?
The issues panel lists each problem with its line number — for example a row with more values than columns, an unclosed parenthesis, or an empty value — while all valid rows are still converted.
What happens when the INSERT has no column list?
Rows become objects keyed by the listed column names; without a column list the tool generates column_1, column_2, and so on. All parsing happens locally in your browser.
