I am facing an issue while converting PDF to Excel file suing ASPOSE API. My scenario is to create a single sheet Excel file for all the pages exist in the PDF. I am creating xls and xlsx file. While opening xls file it shows error (for reference please check XLSFileError.png file). When we open the file through option “Do you want to open it anyway”, it shows all the content in single sheet. But when we close this file it always ask “Want to save your changes”. Somehow Aspose API is creating corrupted Excel files. Also we are not able to open XLSX file created from ASPOSE API. We are getting error which you can check in file “XLSXFileError.png”.
I am attaching two PDF file with converted XLS and XLSX files. Also I am attaching java code and error png files for references. Please check and let me know how we can sole this.
