About
The SQL to JSON Converter allows developers to quickly transform relational database dumps (specifically INSERT INTO statements) into a JavaScript Object Notation (JSON) format. This is particularly useful when migrating data from systems like MySQL, PostgreSQL, or SQL Server to document-based stores like MongoDB, or when mocking data for frontend applications.
Instead of manually reformatting thousands of rows, this tool parses the column definitions and value sets to generate a compliant JSON array of objects.

- Step 3. Parse value groups
(val1, val2), (val3, val4). - Step 4. Map keys to values:
{ "col1": val1, "col2": val2 }.

Frequently Asked Questions
The tool works best with standard ANSI SQL `INSERT` statements containing an explicit list of columns, e.g., `INSERT INTO table (a,b) VALUES (1,2);`. It supports multiple value groups (batch inserts).
The parser attempts to distinguish numbers from strings. Unquoted numeric values become JSON numbers. `NULL` keywords become JSON `null`.
No. The conversion happens entirely within your browser using JavaScript. No database data is transmitted over the network.
