Step-by-Step Instructions to Change Date Format

Accessing Format Cells Dialog Box

The Format Cells dialog box in Excel is a gateway to extensive formatting options, including date formatting. To quickly access this toolbox, I often use a keyboard shortcut. For Windows, it’s as simple as pressing Ctrl + 1, and on a Mac, I would press Cmd + 1.

Doing this brings up the Format Cells dialog box immediately, saving me from navigating through the menus. Once the dialog box is open, I have the liberty to navigate through various tabs and explore a plethora of formatting features, from altering number formats to adjusting font styles and even applying borders and fills.

It’s a comprehensive tool that can elevate the presentation and accuracy of data in Excel.

Choosing from the Predefined Date Formats

When changing the date format in Excel, I often start with the predefined formats available in the Format Cells dialog box. After opening it, selecting the ‘Number’ tab, and clicking on ‘Date’ in the category list, a range of date format options appears.

Here, Excel provides numerous choices, from short date styles like “03/14/2021” to longer, more descriptive formats such as “Sunday, March 14, 2021”.

These predefined formats cater to various regional settings or standard preferences, which can be helpful if you’re working with a diverse audience. I simply select the desired format from the list, hit ‘OK’.

All selected cells update instantaneously.

It’s a straightforward process that can drastically improve the readability of your data.

Creating a Custom Date Format

Sometimes, the default date formats just don’t cut it, especially when you’re aiming for a specific presentation of dates in your spreadsheets. Luckily, creating a custom date format is a breeze once you get the hang of it.

After bringing up the Format Cells dialog box, I choose ‘Custom’ from the ‘Number’ tab. The groundwork for any custom format is based on a combination of date and time codes that Excel recognizes. For example, if I input “dd-mm-yyyy”, Excel will showcase the date as “05-03-2023”.

I can even spell out the day of the week by adding “dddd” at the start.

Excel’s flexibility truly shines here; I can create virtually any format like “Day: ddd, Month: mmm, Year: yyyy” to get “Sat, Jan, 2025”. Once I’ve keyed in my custom format, I click ‘OK’, and just like that, my data conforms to my tailored specifications.

This level of customization fosters a personalized feel and can be effective in delivering precisely formatted data to my audience.

 

Troubleshooting Date Format Issues

Sometimes, Excel doesn’t recognize my data as dates, especially if the dates were imported from another program. When this happens, I use the Text to Columns feature:

STEP 1: Select the problematic column.

STEP 2: Go to Data > Text to Columns.

STEP 3: Choose Delimited, and click Next.

STEP 4: Select Date as the column data format.

STEP 5: Click Finish. Excel converts the text to proper dates.
