Regarding Formatting the Excel sheet using EPPlus in C#
Question
I have been working on Excel Sheet Formatting using EPPlus. I am able to create group when the Excel Sheet is in a ordered one .But if the input comes unordered and I have to group then I am facing issue.
The Excel input looks like in the problematic sceario:
Field1 Field2 Field3
1 XYZ ABC
3.1 PRQ SDE
1.1 AB ST
1.2 MN RT
like wise and all 1 related row should be at one group like in ascending order.
I have written the below which if sorted works fine but not able to figure out if the input is jumbled up/ not sorted.
Here is my code.
Thanks for your help.
