Specifics

Is it possible to export TM with tags which were created during project translation or added to segments after import?

It does not matter how the tags have been created. Once a given TM record has tags, they will be visible in the exported TMX file.

Is it possible to export TM with segment ID in XLSX?

It is not possible. The segment ID will not be visible in the generated XLSX file (please see XP-34933). The segment IDs will be visible in the metadata if you generate a TMX file.

Is it possible to export segments from TM that contain a specific word?

It is not possible, you can only search for them in TM Manage tab.

Is it possible to export TM based on a creation date\modified date?

It is possible through REST API. For more information see the REST API documentation on cloud XTM Connect SDK - REST API and our article REST API. It is also possible through SOAP, with the ExportTM method.

Are tags visible in the exported TM?

Yes. If a given TM record contains any tags, it will be all visible in the exported TM in prop elements: <prop type="tagGroup">Example_tag</prop>.

Is there a back-end option for simple export, that would exclude duplicates?

No, there is no such option. However, it would be possible through custom development (an external tool to cut out duplicates).
