In this article, we will show you how to: Tasks like spreadsheet consolidation, data cleaning, and predictive modeling can be done in minutes using a simple Python script that writes to an Excel file.Įxcel users can also create a scheduler in Python that runs the script automatically at different time intervals, dramatically reducing the amount of human intervention required to perform the same task again and again. These drawbacks can be solved by automating Excel workflows with Python. Surveys show that 93% of Excel users find it time-consuming to consolidate spreadsheets and that employees spend approximately 12 hours each month just combining different Excel files. For instance, if you need to replicate an analysis on multiple Excel files every week, you would have to open them manually and copy-paste the same formulas over and over. You can run into serious performance issues when trying to perform complex operations on a lot of data entries in Excel, especially if your formulas and macros are not optimized for performance.Įxcel can also become very time-consuming if you need to perform repetitive tasks. One limitation of Excel is its inability to handle large amounts of data. However, despite Excel’s undisputed strengths, the tool comes with its own set of drawbacks, making it, at times, inefficient when performing specific tasks involving huge datasets.

You can also perform predictive modeling tasks like regression and clustering using Excel. In fact, research in 2019 found that roughly 54% of businesses use Excel to perform arithmetic operations, analyze data, create visualizations, and generate reports.

Whether you are a student or a working professional, chances are that you have used Excel to work with data and crunch numbers.
