As business requirements evolve, certain features are expected to evolve as well. That was the case for me few days ago when I had to implement a feature where Django model's data are converted to .xlsx excel format and sent, as attachment, to a provided email address literally. It was a big problem for me to figure out how to do this with that file extension as most available solutions were using the old .xls excel file extension and none really talked about sending excel file as attachments of an email sent via Django. To solve this problem, I looked at a similar solution by Vitor Freitas who used xlwt to export Django model's data to .xls excel file format and served it as response data to the user for download. Though a great companion, I needed a different file extension and was solving a slightly different problem. From further research, I came across Working with Excel Files in Python, from Working with Spreadsheets using Python, which recommended openpyxl for "reading and writing Excel 2010 files (ie: .xlsx)" so I decided to try the package out. This experience birthed this article where I utilized coingecko's api to periodically fetch cryptocurrency's coin's data, store the data in a database, and then display as well as allow users to extract the data to excel files sent to any email address provided. It's my deepest hope that you will find it helpful.
