Scrape any table or listing into CSV or Excel where numbers are numbers and dates are dates. No account, no limits, no tracking. Most scrapers hand you text. $4.2M arrives in Excel as "$4.2M", 268 points as "268 points", 2 hours ago as "2 hours ago" — every column left-aligned, nothing that sums or sorts. Datum works out what each column actually holds and exports it properly typed. WHAT IT DOES • Finds tables, card grids, listings and feeds with no setup • Handles records that span several rows, which other scrapers return as blanks • Crawls pagination: next links, numbered pages, URL patterns, load-more, infinite scroll • Names columns from the page itself • Separates link text from link target • Collects several regions at once, each as its own sheet • Exports CSV, Excel and JSON; copies as TSV • Scrapes a list of pages you paste, or a pattern like /products/page/1..20 • Filters rows before export, so you never clean up afterwards • Remembers your column setup per site, exportable as a JSON file • Saves a crawl as it goes, so a failure never costs you what you already had WHAT IT DOESN'T DO No proxy rotation, no fingerprint spoofing, no bot-defence evasion. Delay controls with jitter are provided so crawls stay considerate. HOW TO START IT Click the toolbar button, right-click the page and choose Datum, or press Alt+Shift+W. The panel opens across the bottom of the window. PRIVACY No host permissions. Datum can't touch a page until you click its button on that tab. It makes no network requests at all — no analytics, no error reporting, no account, no cloud, no page quota. Open DevTools and watch.
