Regex Batch Replacer

Regex Batch Replacer is a straightforward piece of software designed to help you find and replace words across multiple text documents at the same time. It supports regular expressions (regex).
Besides the fact that it supports bulk processing, it gives you the possibility to filter files by name or type.

Find and replace text in multiple text documents

This type of software comes in handy to users who typically work with text documents and have to correct mistakes or simply update files by taking into account specific keywords. Instead of manually opening each file to search and replace text, it's easier to turn to this tool.

Just download and run the app

Regex Batch Replacer is wrapped in a single .exe that can be saved anywhere on the disk and just double-clicked to open the main app window. Also, you can keep it stored on a USB flash drive to directly run it on any PC without complications.
However, it depends on .NET Framework to work properly, so make sure to have this software framework installed.

Simple UI with no exciting graphical elements

As far as the GUI goes, Regex Batch Replacer keeps things simple. It has just one window displaying all settings available, which aren't that many to begin with. Nevertheless, you can get a glimpse of everything before starting the configuration.

Configure search settings easily

You can enter the keyword to look for as well as the one to replace it with. Then you can specify the filter, whether you want to process only files matching a specific name or a specific type, as well as indicate the directory whose containing files you want to scan. Subfolders can be either included or excluded.

No messages on task completion

Once the operation is over, the status bar says "Done! Ready" and there are no other indicators to let you know whether or not the task was successful. You can just open the files in question to check results.
Unfortunately, the developer didn't specify the type of text files supported by this application. It worked with TXT in our testing. Although it's not much to look at, Regex Batch Replacer offers a simple solution for finding and replacing words in multiple text files at once. It worked smoothly on Windows 10 in our tests.
