Fast first-pass static HTML accessibility checks mapped to WCAG 2.2. Not a replacement for manual testing or a full axe-core run.

Audit thousands of URLs for broken links, redirect chains, and final destinations in one run. Built for SEO audits, site migrations, and link monitoring — you only pay for URLs actually checked, never for timeouts or errors.

Upload a CSV file and get back a clean version: duplicate rows removed, whitespace trimmed, null-like values normalized, empty rows dropped. Includes a stats report of everything that was fixed.

Merge two CSVs (or dedupe one) into a single clean file with duplicate rows removed. The natural companion to CSV Data Cleaner for combining exports and lists.

Check DNS records (A, AAAA, MX, TXT, NS), SSL certificate expiry, and key security headers for domains. Built for agencies and DevOps teams monitoring client sites.

Extract tables from web pages into structured rows. Perfect for researchers, journalists, and finance teams who need web tables as clean data.

Convert between JSON arrays and CSV in both directions. JSON objects are flattened (nested keys become dot-notation columns), CSV values get light type inference (numbers, booleans, nulls).

Extract text from PDF files page by page. Ideal for RAG ingestion, legal and finance document workflows, and research.

Strip web pages (or pasted text/markdown) down to clean raw text: HTML tags, scripts, styles, markdown artifacts, and excess whitespace removed. One dataset record per page plus a job summary. Ideal for building LLM-ready corpora and content pipelines.

Parse RSS and Atom feeds and extract new items with titles, links, and publish dates. Great for news aggregation, content monitoring, and LLM data pipelines.

Extract title, meta description, headings, canonical URL, Open Graph tags, and word count from web pages. Ideal for SEO audits and content inventories.

Turn any list of websites into a lead list: extracts email addresses, phone numbers, and social profile links from every page. Built for lead generation, sales prospecting, and agency outreach — you only pay per contact actually found.

Look up domain registration data (registrar, creation and expiry dates, status, name servers) via the RDAP protocol. Built for domain investors, brand protection, and lead enrichment.

Resolve shortened URLs to their final destinations and show the full redirect chain. Handy for affiliate marketers, security teams, and analysts.

Repair malformed JSON documents and return the repaired JSON, parsed value, and repair details for each attempted document.
