Turning Numbers into Dates in Excel: A Step-by-Step Guide

Are you struggling to convert numbers into dates in Excel, especially when working with multiple sheets named after months? Fear not! In this guide, we will guide you through a simple VBA solution. By the end of it, you'll be able to automatically convert numbers in your Excel sheets into properly formatted dates for each month.

The Challenge

Imagine you have an Excel workbook with 12 sheets, each representing a month (from "jan" to "dez"). Your goal is straightforward: you want any number entered in column A of these sheets to be automatically transformed into a date format. For example:

If you type 5 in cell A15 of the "jan" sheet, it should display as 05/01/2024.

If you type 12 in cell A17 of the "abr" (April) sheet, it should convert to 12/04/2024.

The Solution: Using VBA

To achieve this, you can use a short VBA script that will check if the value you input in column A is valid for the corresponding month and then convert it into a date. Here’s how to set it up:

Step 1: Open VBA Editor

Press ALT + F11 in Excel to open the VBA Editor.

In the Project Explorer, find ThisWorkbook.

Step 2: Enter the VBA Code

Insert the following VBA code into the ThisWorkbook code sheet:

Step 3: Understand the Code

Let’s break down what this code does:

Defines the Month Array: It lists each month by its abbreviated name in Portuguese.

Checks the active sheet: The code tests if the sheet name matches any month.

Validates the input: It checks if the entered number is a valid day for the respective month.

Converts the number: If valid, it converts the number into a date format using DateSerial.

Step 4: Save and Test

Save your workbook, making sure to choose a macro-enabled format (.xlsm).

Test by entering a number into column A of each sheet. You should see the numbers convert into dates formatted as dd/mm/yyyy.

Conclusion

With this simple VBA code, you can effectively automate the conversion of numbers into dates based on the corresponding month sheets in your Excel workbook. This not only saves time but also reduces the risk of errors in date formatting.

Now you can focus on analyzing your data rather than formatting it!
