Very Useful

This is a very useful app that saves me a lot of time.

I use it to generate databases from the unordered output of my tags from another app. Tags are great but sometimes I need an oldfashioned spreadsheet. This app lets you generate comma or tab delimited text files from the data in txt documents using prefixes and suffixes that you can then import to programs such as Excel. Be sure to check the help files on the website, and use the trial version on the developer's website to check if the app works for your kind of input data.

Some small start-up problems were quickly addressed by the developer, who is very responsive to concerns.

I really like it but...

This is a very useful aplication indeed, the only thing that I would like to see in a future realease is the capacity to read very large text files; I tried using it with a larger file and it colapsed even though I have 18 GB of RAM and no other aplication running.

I think that the way the unix command “more” works is the way to solve this problem because it reads sequentially the file and does not load all in the memory.

I think that if you fix this you deserve all 5 stars, but for now I will give you 4 stars hoping you make this product better than it is now.

Great utility - Easy to use

This app is really effective and easy to use! Saved me hours of work by automating the data extraction process of html pages in the area of chemoinformatics.
It would be nice to see some post-processing feature on the extracted data. Particularly when extracting html data, one might encounter simple tags like subscript (<sub>) or superscript (<sup>) and want these removed. This can be done in any text editor using find/replace so it should be relatively easy to implement.
