Merge attendee lists


If you’ve got multiple attendee lists that you need to merge into a single list, you’ve got several things to think about.

[unordered_list style=”bullet”]
  • Do you need to have unique records in the finished, merged, data?
  • Do the columns in each Excel file/worksheet match?
  • Are you looking to take values from columns in one sheet to add to rows in another?

If you answered yes to any of those questions, you may be in for a bit of a hard time (or copy & paste hell as I like to call it!).

If you have lots of attendee lists to merge, you may be there for a while…

But, you’re in luck! – we will do the merge for you for only $79. Just click the ‘Get started now’ button on the right to get us started.

We had 15 spreadsheets in different formats with differing columns that we needed to be merged and de-duplicated into one data set. It would have taken days to do it manually.
Using Joined-up Data it was easy to get the data into the shape we needed. It was quick and simple for us, and we were delighted with the result.
