Processing large files

Is there a way to extract the content of doc, docx, xls, xlsx, ppt and/or pptx without loading the whole file in memory?, we need to extract content of large files without consuming much RAM

We are afraid that there is no such option and you need to import the whole document (Words and Slides) to respective DOM. However for Aspose.Cells you may visit the following article and see if it fulfills your requirement or not. Please feel free to write us back if you have any other query in this regard.
