How to use

  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.

Limits

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）

What is TOML?

A config format used by many tools (e.g. Cargo, pyproject). This toolkit parses/formats it locally.

TOML → JSON?

Yes—parse TOML then emit JSON for APIs that expect JSON.

Data uploaded?

No. Parsing uses the self-hosted toml-lite helper.

Invalid TOML errors?

Check key quotes, multiline strings, and table headers ([section]).

Binary values?

Focus is text configs; prefer hex/base64 elsewhere for binary blobs.
