JSON to PostgreSQL Query Builder
Paste JSON data, visually select the fields you need, and generate PostgreSQL JSONB queries instantly. Supports arrow notation and path functions.
PostgreSQL JSONB Operators
->Get JSON object field (returns JSON)->>Get JSON object field as text#>Get JSON at path (returns JSON)#>>Get JSON at path as text@>Contains (for filtering)?Key exists checkWhen to Use
- Querying nested JSON stored in PostgreSQL JSONB columns
- Building complex extraction queries without memorizing syntax
- Migrating from NoSQL to PostgreSQL with JSON data
- Learning PostgreSQL JSONB operators and functions
Pro Tips
- Use ->> for text extraction (needed for WHERE comparisons)
- The -> operator returns JSON, while ->> returns text
- GIN indexes work best with @> containment queries
- Path functions are more readable for deeply nested data
JSON to PostgreSQL Query Builder - Technical Details
PostgreSQL provides powerful JSONB support for storing and querying JSON data. The -> operator returns JSON, while ->> returns text. For nested paths, use #> and #>> or the jsonb_extract_path functions. This tool helps you build these queries visually without memorizing the syntax.
Command-line Alternative
-- Arrow notation
SELECT data->'user'->>'name' FROM users;
-- Path function
SELECT jsonb_extract_path_text(data, 'user', 'name') FROM users;
-- Containment query (uses GIN index)
SELECT * FROM users WHERE data @> '{"status": "active"}';
