I'm currently 2 separate TEXTJOIN functions to return all values in table rows (which aren't blank) and to return the headers associated with these.
To extract values (Output1):
{=TEXTJOIN(" + ",TRUE,IF(C7:XL7<>0,C7:XL7,""))}
To extract headers (Output2):
{=TEXTJOIN(" + ",TRUE,IF(C7:XL7<>0,$C$5:$XL$5,""))}
Current outputs are something like:
name project1 project2 Output Output2
User1 0001 0001 project1
User2 0002 0003 0002 + 0003 project1 + project2
User3 0001 0001 0001 + 0001 project1 + project2
When what I really want is one single output, with the value header (in round brackets), before moving onto the next column:
name project1 project2 Output
User1 0001 0001 (project1)
User2 0002 0003 0002 (project1) + 0003 (project2)
User3 0001 0001 0001 (project1) + 0001 (project2)
Is somehow merging the two formulas above possible to output something similar to this? Array formulas make my head spin.
You don't need to ARRAY enter the formula IMHO.
You can try below approach:
=TEXTJOIN(" + ",TRUE,C7:XL7&IF(C7:XL7<>""," ("&$C$5:$XL$5&")",""))
PS: I have tested this formula in web-version of Office 365 where it doesn't need ARRAY entry to show the results.
