Hi,

You can validate file extensions by first using the **Get File Name** plugin to extract the file name from the path. Then, use the **Split** or **Formula** plugin to separate the extension using `.` as the delimiter. Once the extension is extracted, apply the **Filter Rows** plugin to check whether it matches the required formats (e.g., `xlsx`, `xls`, `csv`).
