How to upload only the specified line of the Excel file

My app uses FlatFileImporter to upload over 10,000 lines of excel files. However, uploading takes time, so we are investigating ways to speed up processing. Is there a way to speed up the process, such as specifying the line you want to upload, like the title?

Not out of the box. It would require you to make a modification in the flatfile-module by yourself.

If you want to speed up the process, your best bet is trying oData, which is the import technique having the best performance.
