FAQ and Troubleshooting

Is the extension free?

Yes, the basic functionality of the Market Ninja parser is completely free for all users.

Which websites does the parser support?

Currently, only Wildberries, Ozon, and Lamoda are supported. On other websites, the extension will show a Website not supported message. Read more about this in the Supported Websites section.

Why is parsing slow?

In Extended Data mode, the extension makes a separate request for each product. To prevent the marketplace from blocking you for suspicious activity, we intentionally add random delays between requests. This ensures safe operation.

Data is not being collected

This can happen, for example, if the marketplace website requests a robot check (captcha).

1. Stop parsing;
2. Refresh the marketplace page;
3. If a captcha appears, solve it manually;
4. Start the extension again.

What to do if the marketplace restricts access (Soft-ban)?

Sometimes marketplaces apply a temporary block (soft-ban) if they detect unusually high activity (for example, when collecting extended data). In this case, pages may stop loading, constantly ask for a captcha, or the parsing process simply freezes.

How to fix this:

1. Clear site data: Press F12 in your browser (or right-click on the page and select "Inspect"). In the developer tools panel, find the Application tab at the top. On the left menu, select Storage, then click the Clear site data button. After that, refresh the marketplace page (you may need to log back into your account).
2. Change your IP address: The easiest way is to turn on a VPN, use your smartphone as a mobile hotspot, or simply restart your home Wi-Fi router.

Why are not all products from the category collected?

Marketplaces (Ozon, Wildberries, Lamoda) technically limit the number of products available for viewing in search results or categories. Even if the site says "Found 50,000 products", only the first few thousand are available for the user (and the extension) to view.

This is easy to verify by going to the last page in any catalog. For example, in the Adidas brand section on Wildberries, there are over 100,000 products, but the last page in the category is the 100th.

Why do I see a #NAME? error or =@IMAGE() instead of images in the Excel file?

The =IMAGE() function is a modern feature and is not supported in older versions of Microsoft Excel. When opened in an incompatible version, Excel fails to recognize the formula, resulting in a #NAME? error or adding an @ symbol.

Suggested Solutions:

• Use Google Sheets. Upload your Excel file to Google Sheets. It has native support for the =IMAGE() function and will display the images correctly without requiring any software updates;
• Use Excel for the Web. Open the file in the free web version of Excel at Office.com;
• Update Desktop Excel. Ensure you are using a Microsoft 365 subscription or Excel 2021 or newer.

Can I close the extension window while it is running?

No. The data collection process runs inside the open window. If you close it, parsing will stop. You can switch to other windows (Alt+Tab), but do not close the extension popup window itself.

Is it safe to use the extension?

Yes, the extension works only in your browser, does not collect personal data, and undergoes strict verification in the Chrome Web Store.
