Here you will find additional tools that may be useful for mass formatting and combining .txt files. For example, multiple .txt files can be imported, formatted, and saved into a single file using the tools here. Additionally, a single file can be split into multiple files, each containing your desired number of URLs.
Many of the options available here are self-explanatory. To filter URLS containing or not containing specific words, click the additional filters button.
1. To start a tools project, add files by clicking the + sign or drag them into the popup window.
2. Choose your desired filtering/formatting options. In this example, I will remove duplicate domains from five .txt files and trim the URLs to their root. E.g., myurl.com/my-page becomes myurl.com.
Stats will be shown at the bottom upon completion.
3. Now, I can choose to export the files directly to a project, save them to a single file, or split.
