Mass-Ads-App-Ads-Checker helps you check ads.txt and app-ads.txt files in bulk. It is built for AdOps work, publisher review, and ad file checks across many sites or apps.
Use it to:
- Check many ads.txt and app-ads.txt files at once
- Find files that do not match the IAB format
- Export results to CSV
- Run checks in your browser
- Review results in a clear list
This app is made for Windows users who want a simple way to run checks from a browser-based tool.
What you need:
- A Windows PC
- Google Chrome
- Internet access for the first download
- Permission to save files on your computer
The app uses Chrome extension features and runs in the browser. That means you do not need to set up a server or install extra tools.
- Open the release page: Mass-Ads-App-Ads-Checker Releases
- Look for the latest release at the top of the page
- Download the Windows file from that release
- If the file is in a ZIP archive, right-click it and choose Extract All
- Open Google Chrome
- Load the extension or app file from the extracted folder if the release includes one
- Pin it to Chrome if you want quick access
- Open the app and start your first check
If the release page gives you an .exe file, download and run that file.
After you install or open the app:
- Start Chrome
- Open the app from the extension menu or the installed file
- Allow the app to open local files if Windows asks for permission
- Keep the browser open while the checks run
- Enter the URLs or file paths you want to validate
For best results:
- Use a stable internet connection
- Keep Chrome up to date
- Close other heavy apps if you plan to check a large list
Paste a list of domains or app file locations into the app. You can check many items in one run.
Click the check button to begin. The app tests each target one by one or in a grouped batch, based on the settings in the release.
The app shows which files are valid, missing, or not in the right format. You can use that list to fix problems fast.
Use the CSV export option if you want to save the results in Excel or share them with a team.
This app focuses on ads.txt and app-ads.txt files. It can help you spot:
- Missing files
- Wrong file paths
- Broken URLs
- Lines that do not match IAB rules
- Seller records that need review
- Files that return the wrong status
It uses strict parsing rules so you get clean results. That helps when you need a reliable audit across many properties.

- ads.txt support
- app-ads.txt support
- Browser-based processing
- CSV export
- Clear pass and fail results
- IAB standard parsing
- Deterministic URL probing

The CSV export helps you move results into common tools.
You can use it to:
- Share results with your team
- Track changes over time
- Sort by status
- Filter problem entries
- Build reports for publishers or account teams
The CSV file is easy to open in Excel, Google Sheets, and other spreadsheet tools.
- Use full domain names when possible
- Check both root domain and app file paths
- Review lines with extra spaces or missing fields
- Save results after each large batch
- Keep a backup of your exported CSV files
If you manage many sites or apps, group them in batches so you can review errors faster.
Check ads.txt files across a network of sites and catch setup problems.
Review app-ads.txt files for apps in release or in live traffic.
Run bulk validation before traffic changes, partner updates, or account reviews.
Test if a file exists, loads, and matches the expected format.
The app checks files that are expected to follow IAB rules. In simple terms, it looks for:

That helps you find issues like missing entries, broken links, and format errors.
