You have a SELECT result and you need it as JSON. Maybe you are building an API mock, seeding a test database, or just want to visualize the data structure. Manually converting column values to JSON objects is tedious and error-prone.
This SQL to JSON converter takes formatted SQL output and transforms it into valid JSON — an array of objects where each row becomes a key-value pair.
The converter parses tabular SQL output and maps it to JSON:
Each row in your SQL output becomes a JSON object. Column headers become property names. This is especially useful when prototyping APIs or building data fixtures.
Building a REST API and need sample response data? Run your SQL query, paste the output, convert to JSON, and use it as your GET /users mock response.
Instead of hand-writing JSON test fixtures, run a query against your development database, convert the result, and save it. Your test data stays in sync with the actual schema.
Moving data from SQL to a NoSQL database? Convert SQL results to JSON as an intermediate format, then import into MongoDB, DynamoDB, or Firebase.
| id | name | email |
|----|---------|------------------|
| 1 | Alice | alice@test.com |
| 2 | Bob | bob@test.com |[
{ "id": "1", "name": "Alice", "email": "alice@test.com" },
{ "id": "2", "name": "Bob", "email": "bob@test.com" }
]It converts the tabular SQL output - the result set - into JSON. Run your query first, copy the output, then convert. The query text itself is not executed and cannot be run here: no database is contacted.
Strings are escaped to valid JSON: double quotes become \", backslashes are doubled, and control characters are encoded. That means embedded quotes, Windows paths, and multi-line text values all survive the conversion without breaking the output.
An array of objects - one object per row, with the column headers as property names. That is exactly the shape an API expects for a list endpoint, so the result can be pasted straight into a fixture file or a mock response.
Yes. Conversion runs in your browser, so there is no server-side row limit and nothing is uploaded. Very large result sets are limited only by your browser's memory - converting a few thousand rows is effectively instant.
Yes, entirely. Your result set can contain customer data, so nothing is sent over the network. Disconnect from the internet after the page loads and the converter still works.
