"There is an option to import an Altium file but it should be an ASCII file." Assuming you mean: "There is an option to import an Altium file **into Cadence Allegro** but it should be an ASCII file." As you can see in the Tutorial: [https://docs.easyeda.com/en/Export/Export-Altium/index.html](https://docs.easyeda.com/en/Export/Export-Altium/index.html)<br> <br> EasyEDA can export to Altium in .SchDoc and .PcbDoc format which is not ASCII. I am not aware of any 3rd party .PcbDoc to ASCII conversion tools.

There are companies offering file conversion services: [https://flex-es.com](https://flex-es.com/?gclid=Cj0KCQiA-eeMBhCpARIsAAZfxZDjQ66ibnPbPW2MCT-mn3m6aImVmFhCDhDtvZUWnovFUrfx0vJkDP0aAr6uEALw_wcB)
