Calquer turns any repeating list, grid, or table on a web page into a clean CSV — without code, an account, or a server. It is a free browser extension for Chrome, Edge, and Firefox that runs entirely on your device.
Why we built it
Getting structured data off the web is still weirdly hard. You either copy-paste rows by hand, learn XPath, or hand your data — and often your clients’ data — to a cloud scraper that processes it on someone else’s server. We thought the common case deserved a tool that is instant, free, and private by default.
So Calquer does its work where your data already is: in your browser tab. It detects the repeating pattern automatically, collects every row across scroll and pagination, and lets you export a tidy spreadsheet. Nothing is uploaded, because there is no backend to upload to.
Who builds it
Calquer is built by M H Tawfik, a browser-extension engineer who works on DOM automation and data tooling, and published by Soft Web Grove. The detection engine is grounded in well-studied data-record mining (MDR / DEPTA) and tree-similarity techniques, adapted to run fast and entirely client-side.
Our principles
- On-device by default. Your data never leaves your browser.
- Least privilege. Only the permissions a page tool truly needs — no “read your data on all sites.”
- No dark patterns. No forced account, no fake urgency, no selling data.
- Honest scope. We tell you what Calquer can and can’t do.
