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.

Convert any color between the common web and print formats in one call. Flexible input, including six or three digit hex and common color names; the answer returns every format at once plus ready-to-paste style strings.

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.

Clean untrusted web markup in one call: strip scripts, event handlers and dangerous attributes to prevent injection attacks, while keeping safe formatting. Three cleaning profiles plus a custom allowed tag list.

Convert CSV to clean, typed JSON by URL or raw text. Auto-detects numbers, booleans, and nulls; handles quoted fields, embedded commas, and custom delimiters (RFC-4180). Fast, stateless, and MCP-ready for AI agents.

Extract every HTML table from any web page into clean, structured JSON — headers and rows auto-detected. Just pass a URL; no scraping code needed. Fast, stateless, and MCP-ready for AI agents.

Validate structured data markup on any web page including JSON-LD, Microdata, and RDFa. Detects Schema.org types, checks for errors, and returns detailed validation results.

JSON Translate API converts text in JSON files to multiple languages, facilitating localization and automatic translation of data for web and mobile applications.

A high-performance text purification API designed for TTS workflows. Automatically cleans messy text and prevents Edge-TTS engine errors.

Scrape public static and JavaScript-rendered web pages into Markdown, text, HTML, links, and metadata with automatic browser rendering and optional caching.

Convert public static and JavaScript-rendered web pages into clean Markdown for LLM ingestion, RAG pipelines, search indexing, and content processing.

JSON Clean API converts JSON documents into a readable format with line breaks and indentations. It supports entries up to 200,000 characters.

Extracts and validates JSON-LD, Microdata, RDFa, and structured markup from webpages or raw HTML for SEO and technical validation.

Convert lightweight markup documents into clean sanitized web markup, styled print ready documents or editable word processor files, with real heading styles, lists, tables and code blocks.

Canonical injection test strings for checking your own escaping: SQL tautology, XSS, path traversal, template injection. Harmless probes, not working exploits. Reproducible seeds.

Fuzz testing input data for validation layers: malformed strings, boundary values, control characters. 16 field types, reproducible seeds; each value explains what it breaks.

Malformed and hostile string test data for input handling: control characters, null bytes, encoding edge cases. Reproducible seeds, and every value explains what it breaks.

Unicode test data for internationalization testing: combining marks, bidi overrides, ZWJ emoji, homoglyphs. Deterministic seeds, and every value explains what it breaks.

Integer and floating-point edge cases: int32/int64 limits, NaN, infinity, denormals, and IEEE 754 rounding. Deterministic seeds, and every value explains what it breaks.

QA test fixtures and CI seed data with reproducible seeds, so pinned test runs return identical rows every time. 16 field types, each value explaining what it breaks.

Boundary value test data for off-by-one bugs: int32 and int64 limits, max-length strings, empty values. Deterministic seeds, and every value explains what it breaks.

Date and time edge cases: Feb 29, DST gaps, year 2038, leap seconds, and quarter-hour UTC offsets. Reproducible seeds, and every value explains what it breaks.

Ensure accurate speech generation with the Precision TTS Text Formatter and Purifier API, perfect for professional applications.

Convert between 12 code and data formats with a single API call. JSON to TypeScript, YAML, XML, CSV, JSON Schema, HTML tables, Markdown, and more.
