JSON Object Array Value Counter

Count each distinct primitive value in a selected top-level array property.

About this tool

Count each distinct primitive value in a selected top-level array property. Paste well-formed JSON into the labeled field and inspect the example before running the operation. The tool validates its required inputs, checks record types and selected properties where needed, and returns a new result instead of changing your source data. Processing runs locally in this browser; input is not uploaded. Compare the output with your intended schema and verify it in the consuming application, because application-specific validation rules may not be represented by these general-purpose transformations.

How to use this tool

  1. Paste the JSON value and any required secondary input.
  2. Set the property or numeric options shown.
  3. Run the tool and verify the output shape before using it.

How it works

JSON Object Array Value Counter parses the input JSON, performs the stated transformation, validates operation constraints, and returns a separate formatted result.

When to use this tool

  • Preparing JSON records and local fixtures.
  • Inspecting or transforming data during development.

Limitations

JSON Object Array Value Counter checks JSON syntax and operation-specific constraints; external application schemas must be validated separately.

Privacy

The input and output of JSON Object Array Value Counter stay in browser memory and are not uploaded by this tool.
