problem writing excel sheet using python

[vineeth menneni]

Hi I am finding it difficult to create a excel sheet using openpyxl or xlsxwriter. The problem is that i am loading a table data from MYSQL db which has 600k rows and 15 columns (approximately 100mb data). The error that the terminal shows is that "MemoryError". I just wanted to know if it is possible to create a excel sheet with the above said data in less than one minute using any packages in python. 

Thanks,
Vineeth
