My excel table is shown above and the config file I used is shown below. After exporting the testcases and requirements get exported. But when I run test case updater no linking takes place.

Could anyone tell me as to why they are not getting linked and what changes should i  make to the config for proper export and linking?

Also apart from Testcaseupdater is there any other tool of linking testcases to requiremnts?
