Towards spreadsheet programming

Microsoft Excel introduced the LAMBDA function in February 2021, which officially made Excel a real programming language. Spreadsheet is not just a pack of buttons and clicks, tips and tricks; there are fundamental programming concepts underneath. This course aims to reveal them to you to revolutionize the way you see and use spreadsheets.

  • Most of the contents presented by the course apply to any spreadsheet software including Microsoft Excel and Google Sheets. All the demonstrations in the course are on Microsoft Excel.

  • Both experts and beginners of Excel are encouraged to enrol in this rare course. As this course presents "fundamentals" of spreadsheets, beginners will quickly become an Excel expert and get a very high starting point.

  • Besides "fundamentals", we made efforts to make this course "practical". We illustrate every concept with carefully selected and concrete examples, which are repeated throughout the course. You could apply concepts, methods, skills and tools of this course immediately to your daily job.

Instructor

Tie Cheng

Tie began learning programming in middle school. After his master's degree, he worked in investment banks where he became passionate about spreadsheets and Excel. He then pursued a PhD at Inria & ENS Paris & École Polytechnique, specifically in spreadsheet language and programming. He is now CEO of Matrix Lead, a spin-off of Inria. They undertake technology transfer and research, and make software, especially programming tools, for spreadsheets. He also gives lectures in universities and companies (see below). In 2021, he decided to carefully make this online course to benefit a larger audience. Although today low-code no-code is a hot topic, Tie believes that there are still lots of people who want to learn coding, master the power of computing and building, and gain this knowledge and intelligence. Tie and his team aims to help these motivated people code better through their software and teaching.

When I used excel before, the main focus was on specific use, such as which function to choose, and there was no clear concept of “programming”. This set of courses has given me a new way of thinking, which allows me to think about how to solve problems from a deeper level, rather than just solving the specific situation on the surface.
