I believe there is a problem with the spreadsheet and jaikoz. Specifically with fields that contain more than one value.
For example: if in artists field I have 2 names and in jaikoz they are nested (so I only see one and the number “2” that precedes it), exporting the spredsheet the two values are visible separated by the “;”
If I don’t make any edit and re-import the file into Jaikoz, this will change the fields without there have been any modification.
This is annoying because it creates unwanted changes for you (losing nested data) and it becomes more difficult to control the actual edit you made with the spreadsheet.
