Excel Skills Simplified: Tutorials That Actually Work
How to Transform Data Types Using Power Query
Power Query makes it easy to change column data types in Excel. You can convert text to dates, numbers to text or whole numbers to decimals. This helps your data work correctly in formulas, charts and reports.
How to Remove Duplicates Using Power Query in Excel
Power Query is a simple and reliable way to remove duplicate rows in Excel. It helps you clean data and keep only the unique records you need for analysis.
How to Split Columns Using Power Query in Excel
Power Query makes it easy to split one column into multiple columns. This is useful when your data is stored in one field, such as full names, addresses or product codes.
How To Resolve Excel Found Unreadable Content in ‘filename.xlsx’
Encountering the “Excel found unreadable content” error can be quite challenging, especially when you’re working on an important project. This issue typically arises due to corrupted files or incompatible file formats.
To resolve this problem and successfully open your Excel file, follow the steps below:
Power Query vs Classic Excel Cleaning: A Simple Before‑and‑After Example
If you find yourself doing the same cleaning steps every time a file arrives, Power Query can probably do that work for you with a single Refresh click.
In this article we will take a small “dirty” dataset and walk through the classic way of cleaning it with formulas, then show how to rebuild the same logic in Power Query.
Copilot vs Formulas vs Power Query: Which One Should You Use in Excel?
Excel now gives you three very different ways to solve most data problems: classic formulas, Power Query and Copilot.
The trick is not to pick a favorite and use it for everything, but to know where each one shines so you do not overcomplicate simple tasks or under‑engineer important ones.
Copilot in Excel: From Raw Data to Clean Table and Chart in 10 Prompts
If you have Copilot in Excel and you are still mostly typing formulas by hand, you are leaving a lot of value on the table.
In this guide I will show you a realistic flow where we start with a messy data dump and use a handful of natural‑language prompts to clean it, analyze it and build a quick chart.
How to Build a Simple Dynamic Dashboard with FILTER, SORT and XLOOKUP
In this tutorial we will build a small but useful dashboard: you choose a region from a drop‑down and Excel updates a table and chart automatically.
We will use three modern tools together: FILTER for subsetting data, SORT for ordering it and XLOOKUP for pulling a few summary metrics into neat KPI cards.
Dynamic Arrays in Excel: FILTER, SORT and UNIQUE for Everyday Work
Dynamic arrays are one of those features that quietly change how you work in Excel, especially if you spend a lot of time filtering and sorting data by hand.
Instead of copying formulas down a column, you enter a single formula and Excel spills the results into as many cells as needed.
In this tutorial we will walk through three core dynamic array functions: FILTER, SORT and UNIQUE, using a simple sales table as an example.
