New Post: Performance issue when generating xlsx file with large amount of data

Hi, We have a requirement to generate xlsx file with two sheets. Each sheet contains around 5 lakhs of data and 10 columns. It is taking more time(more than an hour) to generate excel file.
Please let us know the option to increase performance.
For Java, I have seen SXSSFWorkBook(Streaming POI). Do we have similar option for C#/VB .Net. Please suggest.
