As far as I know, mIRC does not support writing files in ".xlsx" format for reading in Excel. But with the help of third-party tools, you can convert the file ".txt" to ".xlsx".

Yes, because each new user is written to a new row, and an existing record is overwritten to the same row in which it was found. If you want all the lines written in the file to be displayed in order from the largest to the smallest number of channel visits each time the file is opened - you will have to create additional code with the function of constantly sorting and rewriting the file data. But there is a nuance! If there are too many such records over time, I am not sure about good productivity of your mIRC when it performs each new sorting.
