Is it possible to upload just the changes made to file since last time
it was imported/updated to the database.

For Eg:

1. File A has String "One"
2. This get uploaded to mysql table
3. File A is updated and now it has
"One"
"Two"
4. Only "Two" gets uploaded to mysql

Something like rsync that just does incremental transfer. Can we do
this between file and mysql.

AFAIK, MySQL doesn't support differential backups. However, you can
backup and restore individual tables.
