We just upgraded from Apex 5.1 to 20.1 and noticed a changed behavior that I'd like to figure out how to get back to the original. The problem is that now in a Classic Report "Export to CSV" feature, NULL columns are exported as space (" ") instead of an empty string (""). Is there any known way to get back to the empty string functionality? I have users that have built macros around the old file format and are squawking about this change. I've tried stripping HTML with no success and that was the only setting I saw that might influence this. I'd really like to avoid custom coding a new export for them.
