JSON Reader

This Node Is Deprecated — This version of the node has been replaced with a new and improved version. The old version is kept for backwards-compatibility, but for all new workflows we suggest to use the version linked below.

Reads the .json file and parses it as JSON value.

Options

Location: The path/URL to the file to read (supports remote and .json.gz files too)
Output column name: Name of the output column
Select with JSONPath: Select a part of the read JSON if checked
JSONPath: The part to select from the input JSON. Using JSONPath preferably with a single result. (For multiple results new rows will be created from them.)
Fail if path not found: If checked, execution will fail if no such part found. If unchecked and not found, the result will be a missing value.
Allow comments in json files: When selected, /*...*/ and the line comments //, # are interpreted as comments and get ignored instead of causing errors
