RegExp Extractor

RegExp Extractor is an advanced tool you can use to extract information from logs and text files using regular expressions. Geared toward expert users, it enables you to set up rules and run tests.

After a fast setup operation that shouldn't give you any trouble, you're welcomed by a user-friendly interface represented by a large window with a clear-cut structure, where you can quickly identify the available options.

It's possible to indicate one of more source files (TXT or LOG format), include or exclude subfolders from the batch processing job, specify the output directory and filename for saving extracted data, as well as to establish a separate file for saving other lines. All resulted files can be merged into a single one.

When it comes to emails and URL domains, you can set a title, separate information by conditions, sort the output files, as well as enter conditions and rules for the extraction procedure.

RegExp Extractor can be instructed to exit on task completion. Moreover, it gives you the possibility to test regular expressions using any subjects you define. During the extraction job, you can check out the currently processed file, elapsed time, number of total processed and extracted lines, as well as speed (number of lines per minute). There are no other notable settings available here.

It carried out data extraction jobs pretty fast in our tests, during which it remained light on system resources consumption. We haven't come across any kind of stability issues, as it didn't freeze, crash or prompt error messages. However, it's solely designed for experienced users, since its set of advanced options is not intuitive enough for beginners. RegExp Extractor is free for non-commercial use.
