Frequently Asked Questions (FAQ)

What are line sorting and duplicate removal used for?

They are used to tidy up lists. You can remove duplicates from a list of email addresses or IDs, sort a word list alphabetically, or strip blank lines and leading and trailing spaces to make a clean list. They are also handy for cleaning up a single column of a log or CSV.

How is the sort order decided?

You can choose ascending (A to Z) or descending (Z to A). By default it ignores letter case, and lines that contain numbers are sorted in natural order (file2 comes before file10). Turn on "Case sensitive" if you want case to matter.

Is the text I enter sent to a server?

No. Sorting, duplicate removal and the other operations all run entirely in your browser with JavaScript. The text you enter is never transmitted to or stored on a server.
