The free HTML-to-CSV tools quit the moment a page isn't a table

Paste-and-convert tools need a clean <table> already sitting on the page. Real pages are paginated lists, card grids, and JS-rendered results — so the tool returns nothing, and the browser extensions that do grab something hand you misaligned rows that choke your import.

  • No <table>, no luck: card grids, directory listings, and search results have nothing for a table converter to grab.
  • Pagination it ignores: you get page one of forty and have to glue the rest together by hand.
  • JS pages come back blank: the rows aren't in the HTML until the page renders, so the tool sees an empty shell.
  • Dirty exports break the import: smart quotes, unescaped commas, and shifting columns mean your CRM or ETL rejects half the file.

How it works

1

Paste your link(s)

One URL or a whole list — a directory, a category page, a set of listing pages. Paginated or JS-heavy is fine; drop them all in.

One link or hundreds.

2

Describe the rows and columns

Type it plain: "company name, website, phone, city — one row per listing." No selectors, no code. We extract exactly those fields.

Plain English, not CSS selectors.

3

We email you the CSV

AI pulls the data, a human checks it imports cleanly — UTF-8, escaped, one consistent schema — and the file lands in your inbox ready for HubSpot, a database, or pandas.

Import-ready, first time.

Works where table converters can't

Paginated lists, card grids, and JS-rendered pages all become rows. You don't need a clean <table> sitting on the page first.

Import-ready, not just exported

Consistent schema, UTF-8 encoding, escaped delimiters. The file goes straight into your CRM, ETL, ad platform, or BI tool without a cleanup pass.

A human checks it before you get it

AI extracts, a person verifies the rows and columns are right. You're not debugging a silently broken scrape after it's already in your pipeline.

Describe it, we deliver — self-serve

No scraper to build or extension to babysit. Say what you want in a sentence and get the file back, free at the lead tier.

What people pull into a CSV

  • A lead or company directory → import-ready CSV for HubSpot or Salesforce
  • An ecommerce category page → product feed with name, price, SKU, stock
  • A public dataset table → a clean CSV for pandas or BI
  • An event attendee or exhibitor list → outreach CSV
  • A paginated listings site → one combined CSV across every page

Questions people ask

That's exactly what we're for. Card grids, directory listings, search results, and paginated lists all work — you describe the rows and columns you want and we build them, even when there's no <table> for a converter to grab.

Yes. We deliver UTF-8 with properly escaped delimiters and one consistent schema across every row, and a human checks it before it sends, so it goes into your CRM, database, or BI tool without a cleanup pass.

We work on public pages out of the box. If the data sits behind a login, send us the saved HTML or a file export and we'll convert that instead — just tell us the situation and we'll be straight about what's doable.

From a single page to a list of hundreds of URLs. Small jobs come back fast; larger or multi-page extractions take a bit longer since a person verifies the output before you get it.
