JSON Array Pivot Count Table

Build a count pivot with one selected row key and column value from object records.

About this tool

Build a count pivot with one selected row key and column value from object records. Provide valid JSON in the input area and review the example to understand the transformation. The operation checks that selected records and properties have the expected shape and rejects invalid numeric values or malformed options rather than silently discarding them. Results are returned separately from your original input. Processing is local to this browser session, with no upload. Confirm the output structure and downstream schema before using the transformed data in an application or production workflow.

How to use this tool

  1. Paste valid JSON and any comparison input shown.
  2. Set the property names and numeric settings.
  3. Run the operation, inspect the result, and verify it matches your target data model.

How it works

JSON Array Pivot Count Table parses JSON, verifies the required operation inputs, and returns a separate result in readable JSON form.

When to use this tool

  • Preparing data fixtures and API records.
  • Analyzing or transforming JSON collections during development.

Limitations

JSON Array Pivot Count Table checks JSON syntax and documented operation constraints; external schema rules are not inferred.

Privacy
