[data grid] Warnings displayed on browser console on duplicate columns names

[narayanandebitos]

We have observed when we import end user excel worksheet data and loaded into data grid pro component there are certain column names which are repeated. But it throws a lot warnings on browser console. why is this behavior ? and how to suppress the warnings ?

Hey @narayanandebitos, the Data Grid columns definition must have a unique value for the colDef.field property to uniquely identify each of the columns.

Could you expand on how are you importing the Excel data into the Data Grid? If you are using some kind of script to transform the data, make sure the field property doesn't repeat. You could instead use the headerName property to show different names on the view.

However, if you are using the unique values for the field and still seeing the warnings, I'd like to see a reproduction example. You can follow the steps here to prepare one: https://mui.com/x/introduction/support/#bug-reproductions

Let me know if you have further questions.
