Ako používať

  1. Open the tool — Open this LocalKit page and wait for the interactive controls to load.
  2. Provide input — Paste or type your content (or set options). Data stays in the browser.
  3. Run the action — Use the primary button or live controls to generate the result.
  4. Copy the result — Copy the output into your editor, terminal, or documents.

Obmedzenia

Requires JavaScript. Extremely large inputs may slow the browser tab. Results depend on your browser APIs; there is no server-side processing quota because nothing is uploaded.

When to use

When you want a quick, free utility without creating an account or sending content to an online converter.

When not to use

When you need server-side integration, batch automation at scale, or certified compliance tooling.

Privacy note

Tool inputs are processed in your browser only. Theme, language and favorites may use localStorage; hosting may keep standard access logs (IP, UA, URL) without tool payloads.

FAQ（5）

Languages supported?

Generate TypeScript and other common type/struct shapes from sample JSON.

Optional fields?

Inference is heuristic from one sample—null/missing fields may need manual tweaks.

Uploaded?

No codegen server—everything is local.

Nested arrays?

Nested structures are walked; unify conflicting shapes carefully.

Best practice?

Use a representative sample (or merge examples) before generating.
