Thanks for using Aspose APIs.
It seems this is not possible and you will have to use the find and replace feature of Aspose.Cells for your needs. It will solve your issue. Please see the following document for your reference.

Please provide your sample Excel file, sample code, actual output Excel and expected Excel file so that we could look into this issue further. You can create expected Excel file manually using Microsoft Excel and provide it to us. Thanks for your cooperation in this regard and have a good day.
