Adding a Clever Timer to a Spreadsheet

GregShadbolt welcome to the forum.

Your post has been unanswered for 5 days now with 96 views. There is clearly interest. This is usually because instructions/uploads are not clearly presented.

Your samples give no indication of the results (meaningful output) you expect in columns F:J. This will likely need to be hand typed and uploaded in a new workbook. And please provide 4 or 5 examples.

In the meantime all I can do is guess what you expect and here is my guess in the attached. In F3 and copied down.

Formula:

=IFERROR(TEXTSPLIT(FILTER(SEQUENCE(,LEN($B3)-2,2),MID($B3,SEQUENCE(,LEN($B3)-2,2),1)="3"),",",,TRUE,1,""),"No Major Errors")

Thanks in advance.
