#html

Render tabular data as an HTML table, and parse an HTML table back into data. The render endpoint turns a JSON array (of objects, or of arrays) or CSV into a clean, semantic <table> with <thead>/<tbody>, an optional caption and CSS class — every cell HTML-escaped so it is safe to embed. The parse endpoint does the reverse: give it any HTML containing a table and get back the headers, the rows and a ready-to-use JSON array of objects, with entities decoded and tags stripped from each cell. Perfect for emails and reports, dashboards and admin screens, and scraping or migrating tabular content. Pure local computation — no key, no third-party service, instant; up to 2 MB via POST. Live, nothing stored. 3 endpoints. Distinct from Markdown/ASCII table rendering and from generic HTML extraction.

Render BBCode — the [b]…[/b] markup used by forums, bulletin boards, game communities and many comment systems — into clean HTML, or strip it down to plain text. Supports bold, italic, underline, strikethrough, lists, quotes, code blocks, links, images, colour and size. Dangerous URL schemes (javascript:, data:, vbscript:) in links and images are neutralised, so the HTML is safe to display. The to-text endpoint removes all markup for previews, search indexes, notifications and excerpts. Powered by the bbob parser. Pure local computation — no key, no third-party service, instant; send large posts via POST. Live, nothing stored. 3 endpoints. Distinct from Markdown rendering and HTML-to-Markdown conversion.

Make untrusted HTML safe to display. Send any HTML — a comment, a rich-text submission, a snippet from an email or a scraped page — and get back a clean, XSS-free version: <script> tags, inline event handlers (onclick, onerror), javascript: URLs, <iframe>, <style> and anything not on the allowlist are removed. Override the allowed tags and attributes to fit your needs, or drop links entirely. A strip endpoint returns plain text with all markup removed. Pure local sanitization — no key, no third-party service, instant. Live. 3 endpoints. Built for user-generated content, comment systems, rich-text editors, email rendering and any place untrusted HTML reaches a browser. Distinct from a Markdown renderer or an HTML data extractor.

Shrink your web assets. Minify CSS, JavaScript and HTML through one simple API and get back the compact output plus how many bytes (and what percent) you saved. CSS is minified with clean-css, JavaScript with Terser (with optional name-mangling and compression toggles), and HTML with html-minifier-terser (collapsing whitespace, dropping comments and redundant attributes, and minifying inline CSS and JS). Pass the source as a parameter or in the request body (up to 5 MB). Pure local processing — no key, no third-party service, instant. Live. 4 endpoints. Built for build pipelines, on-the-fly asset optimisation, email-HTML slimming, CMS and CDN tooling, and page-speed work.

Convert HTML into clean GitHub-Flavored Markdown. Pass an HTML string, or a live page URL to fetch and convert, and get back tidy Markdown — headings, bold/italic, links, images, lists, blockquotes, code blocks, plus GFM tables, strikethrough and task lists. Script, style and head elements are stripped automatically. Tune the output: ATX or setext headings, the bullet marker, fenced or indented code blocks, inline or referenced links, and the emphasis/strong delimiters; toggle GFM on or off. The inverse of a Markdown-to-HTML renderer. Pure local conversion (the optional URL fetch aside) — no key, no third-party service, instant. Live. 3 endpoints. Built for content migration, web clipping and "save as Markdown", scraping cleanup, CMS import and documentation pipelines.

api.oanor.com/htmltomarkdown-api

A fast, fully-local HTML toolkit: extract structured data from supplied HTML (title, meta description, canonical link, language, Open Graph and Twitter card tags, links, images, headings and word counts), convert HTML to readable plain text, list all links resolved against a base URL, and sanitize HTML with a strict allowlist (scripts, iframes, inline event handlers, javascript: URLs and unknown tags are stripped). It works on the HTML you send and never fetches URLs (for live link previews see the oanor URL Tools API). Input via the query string or the request body, up to 2 MB. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for scrapers and data pipelines, comment and email sanitization, RAG and content extraction, and CMS tooling.

A fast, fully-local Markdown toolkit: render GitHub-flavored Markdown to HTML that is sanitized by default (scripts, style/iframe tags, inline event handlers and javascript: URLs are stripped), strip Markdown down to clean plain text, and extract a heading table of contents with levels, text and URL slugs. Every endpoint accepts input via the query string or the request body (up to 1 MB). Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for CMS and documentation tools, comment systems, static-site pipelines and content rendering.
