ajson

ajson [-mq] jsonpath [file]

ajson is a command-line tool written in Go for querying and evaluating JSON data using JSONPath expressions. It reads JSON from a file or stdin and supports filters, wildcards, recursive descent, and evaluation functions such as avg, sum, length, first, last, and math functions.JSONPath syntax is similar to XPath for XML, with $ representing the root object, . for property access, [] for array indexing or filtering, and .. for recursive descent.

jsonpath

JSONPath expression or evaluation string to evaluate.

Path to JSON file (reads stdin if omitted).

Read input as multiline JSON, where each line is a separate valid JSON object.

Do not print errors to stderr.

JSONPath implementations may vary in supported features. Complex nested queries may be slow on large files. Invalid JSONPath expressions produce errors rather than empty results.

ajson implements the JSONPath query language proposed by Stefan Goessner in 2007, providing command-line access to this popular JSON querying method.
