Error due to auto data type change

[bansikpopat]

I have data in excel and imported the data in powerBI. However, when I refresh the data, I see error in loading the data. Below is the screenshot of my error. 

It is the error of data type mismatch and I want to debug the error. How do I identify which column to look at? I have 300+ columns and 1000+ rows. 

Is there an easy way to figure out which column has the error?

Hi @Anonymous , thank you for your response.

Why do I need to remove the step changed type in applied steps? After importing the data, I am manually changing data type for some of the columns. If I remove it, my manipulations will also be deleted. 

Meanwhile, I will also disable the type detection feature and see if it helps me.

Hi @bansikpopat ,

First way is to remove the step named "Changed Type" under applied steps.

Second way is to disable the type detection option under data load.
