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 check

When 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"}';
