I am looking into a way to create a report based on a periodic Excel sheet I receive. The Excel sheet contains a full data snapshot of a given system. It lists the actual status of certain objects and does not contain any historic data. The report I have on my mind should show the development over time.
I looked into the possibility to upload the Excel sheets. As far as I understand, uploading a new sheet overwrites existing data and I cannot “append” it so last month’s data is shown in January 2025 and this month’s data is shown in February 2025 (and last month’s data is left untouched). Is that correct or am I missing something?
