Look at the error message:

It's pretty explicit: you have a column which contains non-numeric data that you are trying to display in an integer column.

We can't do anything about that - we have no access to your excel data, or to your database ... so look at your data, and find out what it should be, what it is, and why. Then you can think about fixing it.

But we can't do any of that for you!

Hi,

It seems while inserting your Excel data into database, the type convertion is missing, please recheck your Excel data type with SQL datatype.
