    Thanks for your question.

    The consumption of RAM not only depends the size of excel file, but also depends on the content of this excel file. If the data inside are almost the same, the compress rate of the file would be high. In this case more RAM are needed.

    And also would be please provide more details about your scenario? If you do not have to load all the DOM at once, maybe OpenXmlReader or OpenXmlWriter would help you with your jobs.
