The HTML to JSON API is a tool that converts HTML code to JSON format. This can be useful for developers who want to extract data from HTML documents and use it in JSON-based applications. The API takes an HTML document as input and returns a JSON object that contains the same information in a structured format.

This endpoint takes the information (string) as input, and provides the JWT-encoded result (string) as output. The output also includes a copy of the input, and a « status » value. Status is « Ok » or « Error: … ».

Validate, pretty print or minify structured data documents, flatten nested documents to dot notation and back, compare two documents field by field, and convert arrays of records to and from spreadsheet friendly text.

Universal JSON Fix repairs broken or malformed JSON, especially from LLMs like ChatGPT, Claude, Deepseek, Gemini, or Llama. This API ensures reliable parsing by fixing mixed quotes, missing commas, and formatting issues, making it ideal for AI applications.
