Now, I want to confirm if you’re using Aspose.Cells Docker or Aspose.Cells Cloud Docker? and the operating system environment in which it resides.
We are using Aspose.cells Docker. OS in which system environment runs is linux.
Please refer to our chat: link for more understanding as how am i using it.
If you are using Aspose.Cells Docker, you need to consult Aspose.Cells Product Family - Free Support Forum - aspose.com for details support.
And I can only give you some advice, I hope it will help you.
If you use Aspose.Cells convert formats in Docker and save files to folders in Docker, then you need to mount Docker data volumes and map folders in Docker to local folders.
And I recommend uploading directly to the remote server in Docker.
