Excel AI Tools for Data Cleaning: How to Save Time and Improve Data Quality
Data cleaning is the process of identifying and correcting errors, inconsistencies, and anomalies in a dataset. Data cleaning is essential for ensuring the quality and reliability of data analysis and machine learning. However, data cleaning can be tedious, time-consuming, and error-prone, especially when dealing with large and complex datasets from various sources.
Fortunately, Excel has some built-in AI tools that can help you with data cleaning tasks. These tools use artificial intelligence techniques such as machine learning, natural language processing, and computer vision to automate and simplify data cleaning. In this blog post, I will introduce you to two of the most daily useful Excel AI tools for data cleaning, with live web link as example for each tool. These tools are:
· Power Query
· Flash Fill
Power Query
Power Query is a powerful data connection, cleaning, and shaping technology that is a core part of the Microsoft modern analytics suite of business intelligence tools. Power Query allows you to connect to disparate data sources, explore and transform data, and load it into Excel or other destinations. You can use Power Query to convert data between different formats, filter and sort data, remove duplicates and outliers, standardize and normalize data, split and merge columns, apply regular expressions and custom scripts, and more. Power Query also supports data reconciliation and enrichment using various web services and external data sources. Power Query works with data on your local machine, as well as data in the cloud or on-premises1.For More
To use Power Query, you need to enable it from the Get & Transform Data group on the Data tab in Excel. Then, you can launch the Power Query Editor from the Query menu. The Power Query Editor has a user-friendly interface that allows you to apply various transformations to your data, preview the results, and undo or modify any step.You can also write your own queries using the M language, a powerful and expressive data manipulation language1.
Flash Fill
Flash Fill is a smart data entry tool that automatically fills in values based on the pattern or example you provide. Flash Fill uses machine learning to detect the logic or structure of your data, and then applies it to the rest of the data. Flash Fill can help you with tasks such as extracting or combining data from multiple columns, formatting data, converting data types, and more. Flash Fill is fast, easy, and intuitive to use2.
To use Flash Fill, you need to enable it from the Advanced options in the Excel Options dialog box. Then, you can use Flash Fill in two ways: manually or automatically. To use Flash Fill manually, you need to enter an example value in a cell, and then press Ctrl+E to fill in the rest of the values. To use Flash Fill automatically, you need to enter two or more example values in adjacent cells, and then Excel will suggest the rest of the values for you. For more
Conclusion
Data cleaning is a crucial step in any data analysis or machine learning project. Excel has some built-in AI tools that can help you with data cleaning tasks, such as Power Query and Flash Fill. These tools can save you time and improve your data quality, allowing you to focus on the insights and outcomes of your data. I hope you found this blog post helpful and informative.
