Me too facing the same issue when i am trying to upload an excel file with 350+ columns.


Hi @nandukrishnavs@milankRaj


Is it .xls and .xlsb workbooks, or xlsx workbooks? There is a 255 columns limitation when importing data from .xls and .xlsb workbooks. See:

Hi @v-qiuyu-msft,


Thanks for the reply. We are trying import data from .xlsb workbook. 


Hi @nandukrishnavs,


As the blog mentioned in my previous post, it's the limitation for .xlsb workbooks.
