As I know the maximum level for outline in Excel is 8.
How to add more level for outline. My data need to group up to 15 levels.
Can anyone advise me on this matter.
Thank you in advance.
As far as I know, a maximum of 8 grouping levels is permitted in all versions of Excel.
I cannot say how much grouping is allowed within a level.
But the only way to do it is to create the additional groups as subgroups.
Thank you for your understanding and patience
