Problems with downloaded .csv - matrix sum problems

[FONT=&quot]I have performed a study using qualtrics, collected all the results but realized after I had started that I needed some data I hadn't downloaded in the first place. So I downloaded the data from qualtrics in .csv-file, opened it in excel and was to merge the matrix from my previously downloaded data (in which I have had no problems in excel) and the new data-file. I figured the easiest way was to have the two matrix' in its own sheet and have a third sheet where I use a simple =matrix1A1+matrix2A2-formula. But when I do so I get #value! in the sum matrix.[/FONT]
[FONT=&quot]I have tried a lot of different options:[/FONT]

• Formating the data as numbers
• =if(istext(A1);"";A1) and =if(istext(A1);0;A1)
• Paste special
• And so on

[FONT=&quot]I attached the file here so a helpful soul can have a look at the problem.[/FONT]
[FONT=&quot]Thanks for any tips available!

Hi and welcome
Please,do not crosspost your question on multiple forums without including links here to the other threads on other forums.

Cross-posting is when you post the same question in other forums on the web. The last thing you want to do is waste people's time working on an issue you have already resolved elsewhere. We prefer that you not cross-post at all, but if you do (and it's unlikely to go unnoticed), you MUST provide a link (copy the url from the address bar in your browser) to the cross-post.

Read this to understand why we ask you to do this, and then please edit your first post to include links to any and all cross-posts in any other forums (not just this site).
If you have fewer than 10 posts here, you will not be able to post a link, but you must still tell us where else you have asked the question

Do not post any further responses in this thread until a link has been provided to these cross posts.
