Excel Not Sorting Dates: Fixing Common Issues Quickly

Sorting dates in Excel is a fundamental task that can become frustrating when the program doesn't behave as expected. Whether you're managing a project timeline, tracking birthdays, or analyzing sales data, sorting dates in chronological order is crucial. However, Excel not sorting dates correctly can stem from a variety of reasons, from formatting issues to data type problems. In this article, we'll delve into the common issues that cause Excel not to sort dates as expected and provide step-by-step solutions to get your dates in order.

Understanding Date Formats in Excel

Before diving into the solutions, it's essential to understand how Excel handles dates. Excel stores dates as serial numbers, starting from January 1, 1900, which is assigned the serial number 1. This means that each subsequent day is assigned a unique serial number. When you enter a date into a cell, Excel automatically converts it into its corresponding serial number. However, the way the date is displayed depends on the cell's formatting.

Common Issues and Solutions

Issue 1: Incorrect Date Format

One of the most common reasons Excel doesn't sort dates correctly is due to incorrect date formatting. If the dates are not in a format that Excel recognizes, it will treat them as text, leading to incorrect sorting.

Solution:

1. Select the cells containing the dates.
2. Go to the "Home" tab in the ribbon.
3. Click on the "Number" group and select "Short Date" or "Long Date" from the drop-down menu.
4. Ensure the dates are now in a format that Excel recognizes (e.g., MM/DD/YYYY or YYYY-MM-DD).

Issue 2: Dates Stored as Text

Another common issue is when dates are stored as text instead of numbers. This can happen if you import data from another source or if you enter dates manually without using a consistent format.

Solution:

1. Select the cells containing the dates stored as text.
2. Go to the "Data" tab in the ribbon.
3. Click on "Text to Columns" in the "Data Tools" group.
4. In the "Text to Columns" wizard, select "Delimited Text" and click "Next."
5. Uncheck all the delimiters and click "Next."
6. Select "Date" as the data type and choose the correct date format.
7. Click "Finish" to convert the text dates to numerical dates.

Issue 3: Mixed Data Types

Having a mix of date formats or data types in the same column can also prevent Excel from sorting dates correctly.

Solution:

1. Select the entire column containing the dates.
2. Go to the "Data" tab in the ribbon.
3. Click on "Text to Columns" in the "Data Tools" group.
4. In the "Text to Columns" wizard, select "Delimited Text" and click "Next."
5. Uncheck all the delimiters and click "Next."
6. Select "Date" as the data type and choose the correct date format.
7. Click "Finish" to convert all the dates to the same format.

Issue 4: Sorting by the Wrong Column

Sometimes, the issue is not with the dates themselves but with the sorting criteria. If you're trying to sort by the wrong column, Excel will not sort the dates correctly.

Solution:

1. Select the entire table or range of cells you want to sort.
2. Go to the "Data" tab in the ribbon.
3. Click on "Sort & Filter" in the "Data Tools" group.
4. In the "Sort" dialog box, select the correct column containing the dates.
5. Choose the correct sorting order (e.g., "Oldest to Newest" or " Newest to Oldest").

By following these solutions, you should be able to resolve the common issues that prevent Excel from sorting dates correctly. Remember to always ensure that your dates are in a format that Excel recognizes, and that you're sorting by the correct column.
