Needing to merge four exported CRM csv worksheets, it was a daunting task and I would consider myself a power Excel user. Excel seemed to make it harder than it needed to be so a quick browse and I came upon Exmerg which brought together the fields easily. A quick “concatenate and sort” afterwards and I saved hours of painstaking copy and pasting. Thanks!

Really love that the site is user-friendly and easy to use but yet is really powerful under-the-hood!
The tool was exactly what I needed! It worked flawlessly and was extremely easy to use. Thank you!
I’ve always struggled with how to merge multiple Excel files into one without resorting to some sort of statistical program like SPSS. Your website did the job BEAUTIFULLY. I bookmarked it and will be returning the next time I need to do something like that.
