Given two email lists, clicking culls non-email addresses, sorts, and removes duplicates. It also combines the email lists and compares them for email addresses in common and for email addresses not in common. The combining feature could be thought of as a “sort / merge” function.
1. Click .
2. “Copy/Paste” your own two email lists into the first two text boxes.
3. Click .
4. “Copy/paste” from the bottom six text boxes as needed.
NOTE: This web page is also useful for sorting and eliminating duplicates from a
single email list. Simply leave the “Email list B” text box empty.
NOTE: Despite the small size of the text boxes above, this web page is capable of handling very large email lists! 1000 email addresses / list: no problemo! :-)
NOTE: One thing that you may find annoying about this web page is that if you simply want to scroll through one of the email lists in the top two text boxes, it is falsely assumed that you are about to make modifications, so the output (bottom six) text boxes are cleared. To reverse this, simply click .
NOTE: This web page was created using Notepad. Except for the background image file the keyboard command JavaScript file and the font / color data JavaScript file, it is completely self contained, and the absence of these three files will not cause any problems. Please feel free to save it to your hard drive using “File/Save as….” Double-click on the newly created “LLBest - Utility - Compare-Combine Two Email Lists” icon (“CompareTwoEmailLists” icon for Firefox), and make it one of your “Favorites.” It will work perfectly even when you are no longer connected to the Internet, or, heaven forbid, when this web page is no longer available!
Questions, comments and suggestions are welcome.
