JSON Editor & JSONPath

A fast, browser-based JSON editor with the tools you actually need: syntax highlighting, inline error checking, one-click Prettier formatting, and a live JSONPath filter pane for drilling into large documents. No setup, no sign-up.

  1. Open the editor at tachicode.dev and paste your JSON.
  2. Format it with Prettier, or fix the inline-highlighted syntax errors.
  3. Open the JSONPath filter pane and enter an expression to query the document.
  4. Read or copy the matching results from the filter output.
  • Edit JSON and JSONC with syntax highlighting and inline error checking.
  • Query with JSONPath in a live filter pane that updates as you refine the expression.
  • Format with Prettier in one click.
  • Schema validation & autocomplete from JSON Schema Store — catch errors and get suggestions against thousands of known schemas.
  • Works offline once the extension is installed.
Is the JSON editor free?

Yes. Tachi Code runs free in your browser at tachicode.dev, with no account required.

Can I query JSON with JSONPath?

Yes. Open the JSONPath filter pane, type an expression like $.store.book[*].author, and the matching results update live.

Can it format or prettify JSON?

Yes — format JSON and JSONC with the built-in Prettier formatter.

Does it validate JSON against a schema?

Yes. Syntax errors are highlighted inline, and JSON files are validated and autocompleted against schemas from JSON Schema Store (or your own schema).
