About this collection

Practical json, xml & data tools, without the clutter.

Structured data is easy for machines to move and surprisingly easy for people to break. A missing comma, inconsistent column or unexpected nested key can stop an otherwise routine task.

Use these tools to make JSON, XML, CSV and TSV easier to read, validate and reshape. Work on a copy when the data is important, and check field names and types after any conversion.

Worth checking: A valid file can still contain the wrong data. Confirm headers, field types and character encoding before importing a converted result.
