Maven Power Challenge - Power Query Clean - Pt1

The Maven Power Challenge has presented a real life case in "dirty data" with power outage data provided between 2002 and 2023. In this video, I look at using Power Query to amend and join data from each year period, then go about cleaning and formatting the event date and time and the restoration date and time. I employ a customised M code to extract dates from multiple format types, whether numeric, or text, or leading with days or months. A link to the calculations is provided below. I then create separate tables for regions, states, and event types, which will be explored in Part 2. #mavenpowerchallenge #mavenanalytics 📱 GOOGLE DRIVE FILE LINK link to formatting M code calculation https://drive.google.com/drive/folder... 📱 SOCIAL MEDIA LinkedIn:   / gerard-duggan-15420a55   Twitter: @DGAnalysis 📔 BLOGS & WRITING Medium:  / duggangerard   DG-Analysis: https://dg-analysis.com/ Maven Showcase: https://mavenanalytics.io/profile/Ger...
