The advised approach here is to copy and paste from a CSV/Excel file to Mac OS "Notes", then copy from Notes to OrgVue.
If troubleshooting an ineffective copy/paste, the advice when working with Excel is to use TSV format, open that in Notes and copy/paste from there.
There is guidance for creating TSVs in this link, note this is an external article not related to OrgVue https://www.papercut.com/kb/Main/HowToCreateTabDelimitedFiles
If this does not resolve your import issue we also advise:
- using column headings which are single row
- ideally use column headings with single (or two) word(s) with no punctuation.
