JSON to SQL

Convert a JSON filter to a WHERE clause, or a JSON object to an INSERT statement. Parameterized output is the default; generated SQL is never executed.

Example

A filter with a comparison and an IN clause:

{
  "status": "active",
  "age": { "$gt": 18 },
  "role": { "$in": ["admin", "editor"] }
}

produces (PostgreSQL, parameterized):

WHERE "status" = :status AND "age" > :age AND "role" IN (:role_0, :role_1)

FAQ

Can I convert SQL back to JSON?: Yes! Click the ⇌ swap button or toggle the Direction dropdown to parse SQL statements (INSERT INTO, UPDATE SET, WHERE) back into JSON.
Which operators are supported?: $eq $ne $gt $gte $lt $lte $in $nin $like $isNull $and $or, including nested $and/$or.
Is the generated SQL safe to run?: Parameterized output never inlines values, so it is safe against SQL injection. Literal mode inlines escaped values directly and should only be used after review.
Does this connect to a database?: No. SQL is generated as text only. It is never executed and no connection is ever opened.
