A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I am located in the Netherl;ands. I am English so have US locale settings.
Previously I imported an xlsx file without problems, but the base system we use has now changed and it is now easier to load csv files.
But that is when the decimal/comma problems started.
Colin,
my article is the solution to your issue, after you've changed the locale in the Power Query options it should be solved.
And as you have dates, you have to tweek the MCode also as I described in the article.
Upload a CSV file if you need further help.
Andreas.
