Excel – Leading zero in CSV on reopen


I have txt file which looks like below

enter image description here

I am importing the txt file in excel using the method shown here. Column Account is converted to text.

enter image description here

Once the data is imported, file looks like below.
I have a requirement to save the file as csv which is then imported by different system.

enter image description here

The problem is on reopen the csv file looks like below. The leading zero in account column disappears. I cannot add ' in front of Account column cells bcoz the system does not accepts. What can be done to preserve the leading zero on csv open/ reopen ?

I m doing this all using vba

Best Solution

This is an unfortunate problem in MS Excel. I could not find any way around this, except to change the format and use xls. I was supplying data to my desktop application from a csv file that could be edited by anyone. Unfortunately, the leading zero problem stayed despite various things I tried. The only reliable method I found was to have a !before the number !00101 so that it was accepted as a string. This was okay for the application(it could replace the ! with nothing), but still the human readability factor was affected.

Depending on your application and use, you might have to use a different format.
