I have written several articles about using python and pandas to manipulate data and create useful Excel output. In my experience, no matter how strong the python tools are, there are times when you need to rely on Excel as the vehicle to communicate your message or further analyze the data. This article will walk through some additional improvements you can make to your Excel-based output by:

  • Adding Excel tables with XlsxWriter

  • Inserting custom VBA into your Excel file

  • Using COM for merging multiple Excel worksheets

Improving Pandas’s Excel Output

Posted by Chris Moffitt in articles   

Pandas makes it very easy to output a DataFrame to Excel. However, there are limited options for customizing the output and using Excel’s features to make your output as useful as it could be. Fortunately, it is easy to use the excellent XlsxWriter module to customize and enhance the Excel workbooks created by Panda’s to_excel function. This article will describe how to use XlsxWriter and Pandas to make complex, visually appealing and useful Excel workbooks. As an added bonus, the article will briefly discuss the use of the new assign function that has been introduced in pandas 0.16.0.
