This is not a great answer, but it should lead you to the right one. I did not write VBA for a solid minute, so I can’t remember the exact syntax, but there is some kind of "psudeo code" for you. I know you can easily implement this in a VBA macro
for all worksheet.rows if cell.value == 0 then cell.value = " " endif endfor
Basically, VBA goes through each line. If the cell in this row is an integer and equal to zero, just replace it with "". It will not be empty, but it seems to be. I think there is also a cell.value is empty property that can clear the contents of a cell. Use the library in VBA, I'm sure there is something there.
Alternatively, if this is a one-time task, you can use a special filter. Just select the filter from the tape and replace all 0 s in a line with a space.
Hope this helps you get started.
