What is the best way to clear all data rows?

[chu86]

Hello.

We load an excel file with a header and potentially already existing datarows.
Mappings are added, and finally the excel will be saved with a collection of data-objects.
We noticed that for the data-rows that were already present in the file, values do not get updated.
What is the best way to load a file and clear all datarows while keeping the header, before saving with new data?

I tried SaveAsync with an empty collection, before doing SaveAsync with my actual collection. This appears to work, but I'm hoping there is a better solution?

Can you elaborate on your use case, perhaps also with a code snippet and a demo Excel file?
