Plateaus can be difficult to convert from lowercase to uppercase letters, but Microsoft Excel 365 provides an easy method to capitalize all letters in a spreadsheet. This quick guide will walk you through the process, step by step. Let's begin.

Before delving into the actual steps, it's crucial to understand that Excel 365 uses two primary functions for capitalization: the PROPER function and the UPPER function. The PROPER function capitalizes the first letter of each word, while the UPPER function capitalizes every letter in a cell. We'll explore both methods in this guide.

Using the PROPER Function to Capitalize Sentences
The PROPER function is essential when you want to capitalize the first letter of each word in a cell. This is particularly useful for titles, proper nouns, or any other scenarios where you want a mix of uppercase and lowercase letters.

To use the PROPER function, follow these steps:
Proper Function Usage

Let's assume your data starts from cell A2 and goes down. In cell B2, type the following formula: `=PROPER(A2)`. When you press Enter, you'll see that the text in cell A2 is now capitalized, with the first letter of each word in uppercase. To apply this to the rest of your data, hover your mouse over the small square at the bottom right of the formula cell (B2). When the cursor changes to a cross, click and drag downwards to copy the formula to the other cells.
Proper Function with Text Wrap
If you're working with long text that doesn't fit within a cell, you can wrap the text to make it fit. To do this, right-click anywhere in your data and select 'Format Cells' (or press Control + 1). In the 'Number' tab, beside the 'Text Wrap' checkbox, click to tick it. Now, your text will wrap automatically to fit within the cell, and the capitalization formula will still work properly.

Using the UPPER Function to Capitalize All Letters
On the other hand, if you need to capitalize every letter in a cell, not just the first letter of each word, the UPPER function is your go-to tool.
Here's how to use it:

Upper Function Usage
Assuming your data still starts from cell A2, in cell B2, type the following formula: `=UPPER(A2)`. When you press Enter, Excel 365 will capitalize every letter in cell A2. To apply this to the rest of your data, click on the small square at the bottom right of the formula cell (B2) and drag downwards.









Upper Function without Text Wrap
Remember, the UPPER function capitalizes every letter, so it doesn't automatically wrap long text. To accommodate long text, simply widen your columns or adjust your row heights as needed.
And there you have it! With these methods, you can easily capitalize all letters in Excel 365. Don't hesitate to experiment with these functions and formulas until you master them. Happy capitalizing!
