Instant Data Scraper is one of the most popular free scraping extensions for Chrome, with around a million users and a 4.9 rating on its Chrome Web Store listing (checked November 10, 2026). For a page with an obvious table or list, it is hard to beat: click the icon, check the preview, download a CSV.
So when it stops working, it is usually not because the extension is broken. It is because the page you are on is not the kind of page it was built for. This guide walks through the five symptoms people run into most, what causes each one, and what to try. The free fixes come first. Only some cases need a different tool.
The short answer
Instant Data Scraper guesses the most relevant table on a page from its HTML structure. Its listing says it uses "heuristic AI analysis of HTML structure" rather than site-specific scripts. That works well on regular lists. It struggles when the data you want is not one repeating block on one page: when the page has several lists, loads results slowly, splits data across pages you have to click into, or when you need the same export again every week.
If a fix below does not help, describe the columns you want in plain English with an AI scraper such as Lection instead of accepting a detected table.
What Instant Data Scraper does well
It is worth being clear about this first, because many "not working" guides are written to sell you something else. According to its own listing, Instant Data Scraper:
- Is free and needs no coding.
- Predicts the most relevant data on the page and lets you adjust the selection if the guess is wrong.
- Detects when dynamic content has finished loading, with a delay and maximum wait time you can change.
- Follows next-page buttons or links and supports infinite scroll.
- Lets you rename and filter columns, then exports CSV, XLS or XLSX.
- Keeps the scraped data in your browser.
If your page has one clear list and you need it once, stay with it. The cases below are where people get stuck.
Symptom 1: It picks the wrong table
What you see: the preview shows the navigation menu, a sidebar of related links, or a footer list instead of the products or results you wanted.
Why: a page often has several repeating blocks. The extension picks the one its heuristics rate as most relevant, and on busy pages (marketplaces, news sites, directories with ads between results) that is not always the one you meant.
Free fixes:
- Use the option to adjust the selection when the guess is wrong, and point it at an item in the list you actually want.
- Scroll the results into view before you open the extension, so the list you want has rendered.
- Remove obvious noise columns in the preview and rename the rest.
If it still fails: describe the data instead of picking a block. In Lection you open the side panel and write, for example, "for each result: business name, rating, number of reviews, phone and the listing link". The AI builds the extraction from that description, so the sidebar and footer never come into it.
Symptom 2: Rows are missing after you scroll
What you see: the page clearly shows 200 items after scrolling, but the export has the first 20 or 40.
Why: infinite-scroll pages add items as you scroll, and some sites also remove items that have scrolled out of view to keep the page fast. If the extension reads the list before new items arrive, or after old ones were removed, rows go missing.
Free fixes:
- Use the extension's infinite scroll option rather than scrolling by hand first.
- Increase the delay and maximum wait time. Slow sites need several seconds per batch.
- Collect in smaller runs, for example one category or one filter at a time.
If it still fails: a scraper that reads each batch as it loads and merges the results avoids the "page removed old items" problem. Our guide to scraping multiple pages without code covers infinite scroll, Load More buttons and how to set a stopping point.
Symptom 3: It stops at page 1
What you see: the export has one page of results even though the site has 30.
Why: pagination needs a next-page control the extension can find and click. Some sites only show numbered page links, change the Next button on later pages, use a "Load more" button that is outside the list, or put page numbers in the URL without a clickable control.
Free fixes:
- Check that the page has a visible Next button or link. The listing says the extension moves to the next page through buttons or links, so when it asks which control moves to the next page, point it at that one.
- If the page number is in the URL (for example
?page=2), you can open each page and export them one at a time, then combine the files in Sheets or Excel.
If it still fails: ask an AI scraper to "collect all pages" from page one. Lection looks for a Next link, a Load More button or a growing feed and keeps going until results stop or it reaches your plan's per-run page limit (10 pages on Free, 50 on Standard, 200 on Pro, per the pricing page).
Symptom 4: The data you need is on each item's own page
What you see: the list shows names and prices, but the phone number, full address, SKU or salary only appears when you click into each item.
Why: a table detector reads the page you are on. Data on linked detail pages is not in that table, and Instant Data Scraper's listing does not describe following links into detail pages.
Free fix: export the list with the link column, then open the links you care about by hand. Fine for ten items, painful for five hundred.
Better fix: keep the link as a column and ask Lection to "open each link and add phone, website and full address". It visits each detail page and adds those fields to the same row. Test on five rows first, because every detail page is an extra page load and uses credits.
Symptom 5: You need the same export every week
What you see: nothing is broken, but you are re-running the same scrape every Monday, downloading a CSV and pasting it into a spreadsheet.
Why: Instant Data Scraper is a one-click export tool. Its listing does not mention scheduling or sending data anywhere except a downloaded file.
Fix: save the extraction and schedule it. In Lection, a saved scrape can run daily on the free plan (delivered by email) or hourly, daily or weekly on Standard, in the cloud with your computer off, and append to a Google Sheet each run. Scheduled runs work best on pages that do not need a login.
Quick reference
| Symptom | Likely cause | Try first (free) | If that fails |
|---|---|---|---|
| Wrong table | Several lists on the page | Adjust the selection | Describe the fields in plain English |
| Missing rows after scroll | Items load late or unload | Infinite scroll option, longer wait | Batch-by-batch collection with a stop point |
| Stops at page 1 | No Next control it can find | Point it at the Next button or link | "Collect all pages" with an AI scraper |
| Fields only on detail pages | Data is not on the list page | Open links by hand | Follow each link and add columns |
| Same export every week | One-off tool by design | Re-run manually | Save and schedule to Google Sheets |
When neither tool will help
Some pages will not work with any browser extension, and it is better to know that up front:
- Logins and paywalls. Browser extensions read what your browser can already show. They do not get around logins, paywalls or CAPTCHAs.
- Security checks. Some sites show a "verify you are human" page to automated visits. Solve it in the tab if it appears; if it appears every time, that site does not want to be scraped.
- Data that is not on the page. If a field only appears in an image or a PDF, a table scraper will not find it.
- Terms of use. Check the site's terms and robots rules, collect only what you need and keep the pace reasonable. Our robots.txt guide for scrapers explains what to look for.
Trying Lection on the page that failed
- Install the free Lection extension and open the page Instant Data Scraper got wrong.
- Open the side panel and describe the columns, including the item link.
- Check the preview against the page, correct anything in plain English, then ask for more pages or detail pages.
- Download CSV or Excel, or save it and set a schedule.
If the page is a plain HTML table, the free HTML Table Extractor does it without any extension. For a side-by-side of the two extensions, see Instant Data Scraper alternative.
When you need more pages per run, Google Sheets delivery or hourly schedules, start the 30-day Standard trial. It is free for 30 days, then $29 per month, a card is required, and it is for first-time subscribers only.
FAQ
Is Instant Data Scraper still free? Yes, per its Chrome Web Store listing (version 1.9.3, updated October 16, 2026).
Why does Instant Data Scraper only get the first page? It needs a next-page button or link it can click. Point it at that control; if the site uses numbered links or page numbers in the URL, export each page or use a scraper that detects pagination.
Does Instant Data Scraper work on JavaScript-heavy pages? Its listing says it detects when dynamic content has finished loading and lets you raise the wait time. Raise the delay first. If rows are still missing, the site is probably unloading items as you scroll.
Can Instant Data Scraper scrape detail pages? Its listing does not describe following links into item pages. Export the links and use a tool that opens each one.
Can I schedule Instant Data Scraper? Its listing does not mention scheduling. For a weekly export to Google Sheets, use a scraper with scheduled cloud runs.
