Could I get hold of the 4.4.3 version of Aspose.Cells please?
Yes, sure, please find attached the version v18.104.22.168 (the binary file Aspose.Cells.dll) as per your demand.
Thanks, unfortunately it did not solve my problem with saving a simple workbook in Excel 2007 xlsx format. The workbook looks ok when opening but I reveive this error:
"Excel found unreadable content in "
I managed to find some slightly newer versions of Aspose.Cells but get the same error.
From which version does this actually work?
Since you are using/trying some older versions of the product (e.g 4.4.3.x), for which we are not sure about Excel 2007 features. For your information, we enhanced/added the Excel 2007 features to certain extent in the later/new versions. So, I am afraid, we recommend you need to use recent recent versions of the product.
I have attached the most recent version/fix for you, please try it (you may comment the licensing code to check whether it works or not) and let us know if it works fine.
