How can I make cells flash with conditional formatting?

Introduction:

Are you having a hard time spotting critical data on your large spreadsheets? Had conversations about making certain cells stand out more? Fortunately, Excel has an impressive feature to solve this problem: Conditional Formatting. With this tool, you can set a condition that, when met, changes the look of the cell. You can highlight cells, make them bold, change the font color, etc. But did you know you can also make cells flash with Conditional Formatting? Let's learn how with ExcelBundle's step-by-step guide!

Relevant Information:

It's important to note that direct flashing cell functionality is not built into Excel. However, we can utilize a clever workaround to create this effect using Conditional Formatting and some Visual Basic for Applications (VBA) code. It should be highlighted that VBA is a powerful Excel feature that allows you to automate tasks and customize Excel functions — it's like Excel's programming language!

All About VBA and Macros:

Macros are essentially small pieces of VBA code - they bring automation to your spreadsheets! You can create a macro to automatically make changes in a worksheet according to the rules pre-defined by you through VBA. For our flashing cells task, we would need to create a simple VBA Macro. But don't worry if you're unfamiliar with it; our guide will assist you!

Steps to Make Cells Flash with Conditional Formatting:

Let's make things easier by breaking down the process into bite-sized chunks. Remember to save your worksheet before trying, as VBA doesn't support undo actions!

Step 1: Enable Developer Tab:

Firstly, you need to visible the Developer tab on the Excel ribbon which doesn't show by default. Click on 'File'> 'Options'> 'Customize Ribbon'. In the right panel under 'Main Tabs', tick 'Developer' and hit 'OK'.

Step 2: Create a New Name:

Next, we will create a new Name in Excel to control cell flashing. Click on the 'Formulas' tab, select 'Name Manager', then pick 'New'. Type 'FlashCell' in the 'Name' box, set 'Scope' as 'Workbook', and input '=NOT(FlashCell)' in the 'Refers to' box. Afterward, press 'OK'.

Step 3: Set Conditional Formatting:

Now, select the cell you want to flash. Go to the 'Home' tab, choose 'Conditional Formatting' > 'New Rule'. Pick 'Use a formula to determine which cells to format', input '=FlashCell' in the box, then set your desired format for flashing (you might want to choose a bright color). Click 'OK' to confirm.

Step 4: Insert VBA Code:

For the final step, click 'Developer' tab > 'Visual Basic'. This will open the VBA Editor. In the editor, click 'Insert' > 'Module', then paste the following code:

Sub StartFlashing()
    If Range("FlashCell").Value Then
        Application.OnTime Now + TimeValue("00:00:01"), "StartFlashing"
    Else
        Application.OnTime Now + TimeValue("00:00:01"), "StopFlashing"
    End If
    Range("FlashCell").Value = Not Range("FlashCell").Value
End Sub

Sub StopFlashing()
    Application.OnTime Now + TimeValue("00:00:01"), "StopFlashing"
    Range("FlashCell").Value = False
End Sub

Exit the VBA Editor and go back to Excel. To start cell flashing, press 'Alt' + 'F8', choose 'StartFlashing', and click 'Run'. To stop it, repeat the process but select 'StopFlashing'.

Tips and Tricks:

If you find the flashing too fast or slow, you can adjust the speed in the VBA code. Just change the "00:00:01" part in the 'StartFlashing' code to the desired time interval. The "00:00:01" means Excel will refresh the flashing every one second.

Conclusion:

While a bit complex, this technique for making cells flash with Conditional Formatting is a useful tool to have in your Excel arsenal! With ExcelBundle's ready-made templates, you can boost your productivity and save time on a variety of tasks. Remember, Excel is not just a data entry tool, but a robust platform that can aid in efficient data visualization and analysis.
