Hello,

I have an Excel performance problem while executing VBA.
My guess is that this may be related to the high volume of lines to be treated (approx. 100,000) in 1 file (A), however, this did not occur before. Would this be a reason why Excel stops responding?
How can I find out the rootcause during this execution? It seems that the new lines that are written in file B, based on file A, stall and that the last line keeps repeating.
Thank you for your help.
