Why data format tools belong together

Every backend, frontend, and integration pipeline pushes data between formats. JSON dominates APIs. YAML owns configs. XML still powers SOAP, SAML, RSS, SVG, and every Microsoft Office document. CSV refuses to die because Excel outputs it. You need a clean toolkit that covers all four, handles their edge cases correctly, and gets out of your way.

The tools in this pillar are built around the same assumptions:

  • Client-side parsing: your data stays in your browser. Paste production JSON without worry.
  • RFC-compliant: JSON 8259, YAML 1.2, XML 1.0, CSV RFC 4180. We don't guess, we follow the spec.
  • Structural over textual: JSON Diff works whether or not key order matches. Formatting differences don't create false diffs.
  • Precise errors: when something fails, we tell you where and why, not just "parse error."

How the tools connect

Common workflows that chain tools in this pillar:

  • Config review: paste YAML config → YAML to JSON → format → paste old version + new into JSON Diff
  • API response debugging: paste raw response into JSON Formatter, then feed into JSON Diff against a known-good fixture
  • Legacy XML migration: format with XML Formatter, then transform the logical structure via your own script to JSON or YAML
  • Bulk data import: paste Excel-exported CSV into CSV to JSON, then validate the shape of the first few records with JSON Formatter
