Hello all,

I have following challange:
I would like to use an external source, for example an stock chart or a weather chart.
Each day I have a new line with new figures.
Visible are only a few lines, maybe one week.

It´s easy to get these data into excel with power query like this tutorial.


My challange is now, that ervery day the website get a new line and the oldest line will deleted.
So, if I refresh my excel file, also here the old values would removed.

Is it somehow possible, that I keep in my table the old value still available?
