Refreshing only partial data in a CSV file

[dikken20]

Hello,
I'm importing data every few minutes from a CSV file which contains about 25K cells with data.
The importing process freezes my PC for about 5-10 seconds which isn't an option.
I thought to myself if I could reduce this freezing time (hopefully to prevent it at all) by refreshing only part of the cells, yet, I'm not sure if that would be the right solution but also I'm not sure how to do it in order to check and test that.



What do you say guys? any suggestions either to the right solution or how to refresh part of the data ?

This appears to be pretty much the same thing you asked earlier? https://www.mrexcel.com/forum/excel-questions/1068789-how-refresh-values-csv-based-condition.html

Nope, both are different questions and would love to have answers to both
One question is how to import and refresh only PART of data from a CSV file,
The Other question is how to refresh an imported data from CSV based on condition or a function rather than using a Sub or manually.

Hope you could see the difference and help me getting some help
