Python for Excel Users: First Steps

Spreadsheets are the tool of choice for data analysis and reporting among a majority of business professionals, who are well-acquainted with common data processes like sorting, filtering, and aggregation.

But spreadsheets have their limitations, which templates and complex formulas fail to solve. For quick, dynamic and repeatable data processes, Python is a helpful addition. The thought of learning a programming language may be intimidating to spreadsheet users, but they know more about data and coding than they think. This course serves to bridge the gap between spreadsheets and Python, by helping users pivot their existing knowledge about data into a new application.

What you'll learn — and how you can apply it By the end of this live, hands-on, online course, you’ll understand:

  • Python’s powerful universe of open-source packages and tools
  • The Python equivalent of common spreadsheet tasks such as PivotTables and lookups
  • Where Python can augment and automate common data preparation and manipulation tasks often done in spreadsheets
  • The role of variables, objects, and functions in Python

And you’ll be able to:

  • Load, view and write spreadsheet files from Python
  • Perform common data wrangling tasks such as sorting, filtering, and aggregation
  • Navigate and execute code in Jupyter notebooks
  • Identify, install and implement useful packages for your needs

This training is for you because...

  • You're an analyst responsible for collecting, analyzing, and interpreting data for business insights.
  • You want to learn how to use Python inside Jupyter Notebooks along with its most common packages.
  • You would like to speed up, automate, and validate your reporting and analysis using open-source software.
  • You’re a spreadsheet user interested in learning more about data science.

Prerequisites What prior knowledge or experience is necessary?

  • You should be comfortable with basic tasks and functions in Excel, including sorting and filtering, and the use of IF statements. Ideally, you've also used conditional aggregates like SUMIF() and COUNTIF() as well as PivotTables and VLOOKUP().
  • No prior programming knowledge needed. As an Excel user, you already know more programming than you realize!
