AI Request Payload Formatter
Format JSON independently, or check a named restricted request profile.
Validation profile: openai-chat-text-2026-10-19 · restricted OpenAI Chat Completions subset. Unsupported means outside this checker. Formatting has no provider-validation guarantee.
Input is processed on this site only when you run the tool. The application does not save inputs or results.

Run the tool to see your result.

UTF-8 text, at most 65536 bytes per input. Tab leaves the editor. Plain text disables syntax colors. Browser textareas may normalize line endings to LF.

A familiar workflow,
with room to focus.
Paste a JSON object. Format or Minify preserves its tokens independently of any provider schema.
Choose Validate only for the named restricted OpenAI request profile.
Review the result; this tool never sends an API request.
When to use AI Request Payload Formatter
Make an AI request object readable while preserving exact JSON tokens, then optionally check its restricted named request profile.
Read the result
Format and Minify are provider-independent JSON operations. Validate is deliberately narrower; unknown fields can be unsupported even though formatting succeeds and an external API might accept them.

Formatting success means valid object JSON. Validation has a separate, explicitly limited meaning.
- Formatting accepts arbitrary object fields and preserves number/string spellings and member order. No provider validation is implied. Unique decoded keys required; 65,536 bytes, depth 64 and 10,000 values.
- Profile openai-chat-text-2026-10-19: a restricted local OpenAI Chat Completions subset reviewed 19 October 2026. A valid result covers this profile only. Unsupported means outside this checker, not rejected by the provider.
- Validate accepts only nonempty string model and the supported messages array, optional boolean stream and 1–16 supported nested function tools with unique names. The 100-property cap is aggregate across tools. Model IDs are not looked up.
- Other API fields and providers are outside the validation profile. No credentials, network calls, model execution, cost estimate or compatibility guarantee.
- Input: 65,536 UTF-8 bytes per text field. Output: at most 524,288 UTF-8 bytes; serialized responses have a separate 1 MiB ceiling. Size/work failures return no partial result.
