Xlwings is a popular open-core library to program Excel with Python. Ever since I created xlwings in 2014, it's popularity has been on the rise and today it's being used by companies across all industries and countries, including many hedge funds, banks and Fortune 500 companies. I am the author of the popular on-demand video course "Python for Excel" and organizer of the xlwings meetups in London and NYC with combined over 500 members. I also regularly blog both on https://www.xlwings.org/blog as well as https://www.xltrail.com/blog. Our team is passionate about Excel and our innovative solutions solve a wide range of "Excel issues" as we typically see them in financial companies/departments where Excel is used for mission critical tasks. Many of our solutions are open-source and free and give you back the fun when working with Excel. Even more important, they allow you to build rock solid (a.k.a audit proof) spreadsheets without having to migrate away from Excel. To name a few examples, we help companies with: ► Python and Excel: Write UDFs in Python and automate Excel via xlwings, our free and open-source Python package ► Reporting: Our template based Excel reporting helps business users to design and change their reports without the need to know Python or change any code ► Testing: Automated (unit) testing of Excel workbooks including continuous integration ► Collaboration/version control: We make Git (the world's most popular version control system) not just work for Excel workbooks, but we also make Git work for business users via http://www.xltrail.com ► VBA code: "Git XL", our free & open-source Git extension, allows you to properly diff and merge (!) VBA code with Git ► REST API: Allow users to access data from your spreadsheets from anywhere or integrate legacy Excel workbooks into web applications via the xlwings REST API
