Does anybody know how to increase the number of rows in preview at power query editor? I wanna split a column based on a delimiter on a dataset >100K rows, but the number of columns which is created is defined by the preview of 1K instead of checking the whole dataset. I'm using an MS SQL View as a source.
Solved! Go to Solution.
It is 1,000, or all of them.
Just click where it says "Column Profiling based on top 1,000 rows." I did this on a 3 million record database and it took about 5min to read in to Power Query and do its analysis, far longer than to just read it in to the datamodel.
However, the number of columns has nothing to do with the number of rows. If the first 1,000 records have nothing in column X, they will show null, not prevent you from seeing the column.
If you've recently added the column, then you need to tell it to REFRESH ALL in the Home Menu, and possibly clear the Power Query cache and have it reload it.
