Hi Trawets, Find your workbook attached, it should do. Please check the accuracy, since your data there are symbols and other stuff in your data, it could match data that don't include dashes or slashes... and the code below should be tweaked. I think you can run it from the vba editor window or ask if it's new to you. Hope it helps.

I would like to know if this can be done full speed using scripting.dictionary or other methods (i'm not looking for an algorithm killer here):) Is anyone looking at this code able to assess my level of vba (it took me 2 hours to produce this) since I don't how far i can use this skill to apply for a job with vba skill require (i'm first an accountant and for now i feel more comfortable with accounting but I do spend a lot of time coding...i'm able to connect excel to database and words and run queries or else however still with some time)?
