When I export a sign-in sheet to a csv it doesn’t include empty rows for entries with no signup. For example, if I have a task with 4 slots but 3 of them are filled then it will only show 3 rows for that task and will not show an empty row for the missing signup. If a task has no signups then it shows one row for the task (with no signup). This makes it impossible to tell how many unfilled slots there are for a task (from the csv).
The export is actually currently working as designed where it will export all of the signups (or at the very least the task with an empty signup if all are empty so all tasks are accounted for). However, I can definitely see the use case for exporting all slots filled or not so that’s a great idea. I’ve included your request on the wishlist of possible future feature improvements although I can’t guarantee when or if it will be included. If you are in need of this feature ASAP, just send a message through the contact form and I can provide a quote for including this feature right away. Thanks!
