5 Ways to Auto-Refresh Excel Without Reopening

Excel users often find themselves in scenarios where they need to update or refresh data automatically without the tedious task of manually reopening the file. This can significantly enhance efficiency, especially for those dealing with real-time data. Here are five ways to auto-refresh Excel spreadsheets:

1. Using Excel’s Automatic Refresh Feature

Excel has a built-in feature that allows you to auto-refresh external data connections:

• Go to the Data tab on the Ribbon.
• Click on Connections.
• Choose the connection you want to refresh automatically.
• Set the Refresh control settings to enable automatic refreshing and specify the frequency.

📌 Note: This method is particularly useful for data from external sources like databases or web queries.

2. VBA Macro for Continuous Refresh

If your data updates continuously or at irregular intervals, consider using VBA (Visual Basic for Applications):

• Open the VBA editor by pressing Alt + F11.
• Create a new module and insert the following code:

Sub AutoRefresh()
    ThisWorkbook.RefreshAll
End Sub

• Use the OnTime function to schedule the macro to run at specific intervals:

Public RunWhen As Double

Sub StartTimer()
    RunWhen = Now + TimeValue(“00:05:00”)
    Application.OnTime RunWhen, “AutoRefresh”
End Sub

Sub AutoRefresh()
    ‘Refresh All Data
    ThisWorkbook.RefreshAll
    ‘Reinitialize the timer
    RunWhen = Now + TimeValue(“00:05:00”)
    Application.OnTime RunWhen, “AutoRefresh”
End Sub

🔄 Note: Be cautious with intervals, as frequent refreshes can affect system performance.

3. Power Query for Scheduled Data Refresh

Power Query in Excel allows for a scheduled data refresh:

• In the Data tab, click on Get Data.
• Set up your data query, and when finished, click on Close & Load To….
• In the Load To dialog, select the option to set a refresh frequency under Data Options.

4. Refreshing With Worksheet Open or Change Events

You can also refresh data when the workbook is opened or when a change is made:

• In the VBA editor, insert a new code module.
• Add an event to refresh data when the workbook opens or when data changes:

Private Sub Workbook_Open()
    ThisWorkbook.RefreshAll
End Sub

Private Sub Worksheet_Change(ByVal Target As Range)
    ThisWorkbook.RefreshAll
End Sub

⚠️ Note: This might slow down the opening of large workbooks if they contain many queries.

5. Add-In or Plugin Solutions

If coding isn’t your forte, consider third-party Excel add-ins or plugins designed for auto-refresh:

• Add-ins like “Auto Refresh” or “Excel Scheduler” can automate the refreshing process.
• These tools typically provide user-friendly interfaces where you can set up refresh intervals, trigger events, or schedule refreshes at specific times.

By employing one or more of these methods, you can keep your Excel data current without the need for manual intervention. Each technique offers different levels of automation, catering to various scenarios:

• The Excel's Automatic Refresh is ideal for when you're dealing with external data sources.
• VBA Macros provide flexibility for user-defined triggers and continuous updates.
• Power Query is excellent for scheduling and managing data refresh from multiple sources.
• Refreshing on Worksheet Open or Change Events ensures data is up-to-date when the user needs it most.
• Add-Ins offer a no-coding option for those less familiar with Excel's programming features.

What’s the advantage of using a VBA Macro for refreshing Excel data?

+

VBA macros allow you to refresh data at user-defined intervals, making it highly flexible and adaptable to specific workflows.

Can I refresh data only when the workbook is open?

+

Yes, you can set up a macro that refreshes data when the workbook opens or when a specific sheet changes.

How do I ensure my Excel workbook does not slow down due to frequent refreshes?

+

Set refresh intervals to longer periods, minimize the number of data sources, and consider using optimized methods like Power Query or scheduled tasks to manage performance.
