Data format management is when you organize and store data in a way that makes it easier to use. For example, when you use a spreadsheet (like Excel or Google Sheets) it is helpful to organize the data into columns and rows. This way, you can easily find the information you need and keep track of records. To help you keep track of the data, you can also add labels to your columns and rows. That way, you know what kind of data is in each row and column and it's easier to find what you're looking for.
