How to make input type= file Should accept only .xlsx and filename contain substring

Question

I want to upload a .xlsx file to my systems with condition that the file name contains a specified string.

For example: I want to upload file whose name contains "Paper", so the file browser should not display files which don't contain "Paper" in their name.

For the example in the photo that I attached in this post, the file 'Order#...' should not be displayed.

How can i do it? Is it possible to implement this idea? thanks.

You can use accept attribute
Try this code

<input type="file" accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" />
