SQL to JSON
Convert SQL INSERT statements to JSON arrays or objects instantly. Supports multi-row VALUES, NULL handling, auto type detection, and pretty print. 100% client-side, no upload.
How does SQL INSERT to JSON conversion work?
The tool parses SQL INSERT INTO statements, extracts column names and row values, then converts each row into a JSON object with column names as keys. Multiple rows produce a JSON array of objects.
What SQL syntax is supported?
Standard INSERT INTO table (columns) VALUES (values) syntax is supported, including multiple VALUES rows, backtick or double-quoted column names, NULL values, numeric values, string values with escaped single quotes, and boolean-like values.
How are NULL values handled?
NULL values are converted to JSON null by default. You can toggle the option to exclude keys with NULL values from the output entirely.
Is my data safe and private?
Yes. All processing happens 100% locally in your browser using JavaScript. No data is ever sent to any server, and the tool works even without an internet connection.
What is the difference between JSON array and JSON object output?
Array output wraps all rows in a JSON array [{...}, {...}]. Object output uses the first column as a key, producing {key: {...}, key: {...}}. Choose based on your downstream API or code needs.
Can this tool handle large SQL dumps?
Yes. The tool processes SQL in your browser with streaming parsing, so it can handle INSERT statements with thousands of rows efficiently without memory issues.
Does it auto-detect data types?
Yes. The tool automatically detects numeric values (integers and floats), boolean values (true/false), NULL, and strings, converting them to the appropriate JSON types.
Why convert SQL to JSON?
JSON is the standard data interchange format for web APIs, NoSQL databases, and configuration files. Converting SQL INSERT data to JSON makes it easy to migrate data between relational and non-relational systems, seed test data, or feed REST APIs.
Can I use this tool offline?
Yes. Since all processing is client-side JavaScript, the tool works fully offline once the page is loaded.
How are escaped quotes in SQL handled?
Escaped single quotes (\'\') within SQL string values are properly unescaped and converted to regular quotes in the JSON output.
How to Use SQL to JSON
Convert SQL INSERT statements into JSON arrays or objects instantly in your browser. Multi-row VALUES, NULL handling and automatic type detection are all processed locally — your data never leaves the page.
- Paste an INSERT statement — single or multi-row VALUES both work — into the input area.
- The tool parses the column list and every VALUES tuple, detecting numbers, strings, booleans and NULLs automatically.
- Switch between JSON array output, where each row is an array, and object output, where rows become {column: value} objects.
- Enable pretty print to indent the JSON for readability, then copy the result into API mocks, tests or migrations.
Columns that look numeric are converted to JSON numbers — if an ID must stay a string, quote it in the SQL before converting.
