File contains corrupted data Details: Binary
File is 33.3mb - I did try splitting this into 2 files yesterday and then was going to append but I had the same issue.
I have just cut the file down to 20,000 rows and it refreshed. Does that mean there's an error in the other however many rows or?
Do we know why it would randomly bring up the error though even though I have worked on it for several hours today with no problems? It was only when I added a conditional column that it appeared to cause an error.
I would be inclined to open a support ticket with MS at the bottom of the Power BI support page. I cannot do that as the file I was having an issue with I got rid of and we moved to a direct SQL access, but it seems clear that there is a glitch in Power BI Desktop with larger Excel files on Sharepoint that started probably with the April desktop update.
