About this tool
JSONPath Tester
The JSONPath Tester evaluates JSONPath expressions against JSON documents with support for filter expressions, array slicing, and recursive descent operators.
• Test a JSONPath expression before adding it to a Spark or BigQuery JSON extraction query
• Extract a nested field from an API response to verify the correct path
• Debug a JSONPath filter expression that is returning unexpected results
• Validate array slicing syntax for a data pipeline JSON transformation

FAQ
What does this tool tell you?
The JSONPath Tester evaluates JSONPath expressions against JSON documents with support for filter expressions, array slicing, and recursive descent operators.
What affects the result most?
Evaluates JSONPath expressions against a JSON document with real-time results. Standard JSONPath operators: $.store.book[*].author, $..price, $[?(@.price < 10)]. Filter expressions: [?(@.category == 'fiction')] with comparison and logical operators.
How should I use the result?
Use the result as a planning baseline. It is generated from the inputs you provide, so varying the inputs shows you the sensitivity of the calculation. Your actual situation may include factors this tool does not model; treat the output as one input to your decision.
