I try to read SpreadsheetML format, but LoadOptions/LoadFormat classes are not found. We use very old version os Aspoce.Cell 4.4.0. Does it support LoadOptions?
Thanks for your posting and using Aspose.Cells.
Probably, it does not support LoadOptions that’s why you are getting this message. Please download and use the latest version: Aspose.Cells
for .NET v126.96.36.199 for your needs.
No, it doesn't support LoadOptions or LoadFormat APIs, you need to use the latest versions of the product for it. I think you may try to use FileFormatType enum instead if it exists in your older version and relevant member is there for SpreadsheetML format, e,.g
Workbook wb = new Workbook();
