#parser

Parse and build URL query strings — with full support for nested objects and arrays. Turn a query string like a[b][c]=1&tags[]=x&tags[]=y into a clean nested JSON object, and turn any JSON object back into a properly-encoded query string. Choose how arrays are serialised (indices, brackets, repeated keys or comma-separated) and whether to URL-encode. Far beyond a flat key=value encoder — it handles the deep structures real web frameworks (Rails, PHP, Express/qs) use. Pure local processing — no key, no third-party service, instant. Live. 3 endpoints. Built for API request construction, parsing complex links and redirects, form-encoded bodies and webhook payloads.

Parse a raw email (RFC 822 / MIME / .eml) into clean, structured data. Send the raw message (or a URL to a .eml file) and get back the sender, recipients (to / cc / bcc / reply-to) with names and addresses split out, the subject, the parsed date, the Message-ID, In-Reply-To and References (for threading), priority, the plain-text and HTML bodies, every header, and metadata for each attachment (filename, content type, size, content-id — never the binary payload). A /v1/headers endpoint returns just the header map. Parsing is fully local (no third-party service) and nothing is stored. Live. 3 endpoints. Built for inbound-email processing, .eml viewers, mailbox import, ticketing and email-automation pipelines. Distinct from address validation and SPF/DMARC checks.

Extract text from PDF documents: the complete document text, the text of every page separately, the document metadata (page count, title, author, subject, keywords, creator, producer, creation and modification dates, PDF version, encryption and outline flags), and a full in-document search that returns the matching pages with hit counts and context snippets. Supply a PDF by public URL, base64 or a raw binary request body; only public http/https URLs are accepted and private or internal hosts are blocked. Pure server-side computation (pdf.js, no third-party upstream, no per-page cloud cost). Ideal for document indexing and search, data extraction and ETL, invoice and contract processing, archiving and content pipelines.

A fast, fully-local cron-expression toolkit (UTC): validate 5-field cron expressions with ranges, lists, steps, month and weekday names and the common @aliases (@yearly, @monthly, @weekly, @daily, @hourly); compute the next N run times for a schedule from now or any start date; and describe a schedule in plain English. Every endpoint accepts input via the query string or the request body. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for schedulers and job runners, devops and CI tooling, and dashboards that show the next run time of a task.

A fast, fully-local XML toolkit: convert XML to JSON and JSON to XML with configurable attribute handling, validate XML well-formedness with line and column error details, and pretty-print XML while preserving element order. Every endpoint accepts 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 system integrations, SOAP and legacy interop, RSS and sitemap processing, config tooling and data pipelines.

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.
