# [DRILL-8108](https://issues.apache.org/jira/browse/DRILL-8108): Excel
Reader Fails with Duplicate Columns
## Description
In its current implementation, if Drill encounters an Excel file which
contains duplicate column names, it will fail to read the data. This PR fixes
this issue by appending `_n` after the duplicate column.
## Documentation
No user facing changes.
## Testing
Added two unit tests.
