I am doing some voluntary work for a local voluntary organisation who rely on donations which have dwindled in recent times so have to get by ...
We have multiple data sources held in Excel tables, which fortunately do have a common key ie email address ...
But we need to combine them into a single table, with a record (row) per email address - with some columns updated from the data sources (1:1 mapping) and some columns updated manually ...
The challenge I've got is i) can I use multiple Power Query queries to update specific columns and ii) in doing so, can I update the table with new records and only changed values in existing records and iii) can I do that without loosing manual (typically comments) entries?
Tentative post at this stage, but if anyone can point me at places that address this, I would be extremely grateful ...
Many thanks ...
