Use the "Refresh All" button to update all data connections in one click; 2. Check data source availability, authentication information and format changes to resolve refresh errors; 3. Set up timed automatic refresh to keep data up to date; 4. Enable more flexible automated control through VBA scripts. Click "Refresh All" in the "Data" tab to update all connections at once, or set shortcut keys to speed up operations; if the refresh fails, check the data source status and structure changes, and handle error connections separately; enable "Auto Refresh every X Minutes" to set appropriate intervals, but only take effect when the file is opened; advanced users can use VBA code to automatically refresh all connections when opening files, improving efficiency and reducing manual intervention.

If you are using Excel to process multiple data sources, such as data from databases, networks, local files, or other external tables, you may often encounter the trouble of "manual updates". In fact, Excel provides a variety of ways to refresh all connections at once, saving the hassle of one point.

Here are some practical methods to help you quickly refresh all data connections.

Refresh all connections with one click: Use "Refresh All"

This is the most direct way. If you have multiple data connections in your workbook (such as Power Query queries, external data tables, OLAP connections, etc.), you can update them all in just one operation:

• Click the "Data" tab on the menu bar
• Find the Refresh All button in the ribbon (usually in the Query and Connection area)
• After clicking, Excel will automatically refresh all data connections in the current workbook.

Tips: You can set shortcut keys for this operation, such as recording a macro, binding it to a key combination like Ctrl Alt R , and refresh it faster in the future.

Pay attention to connection status and error prompts when refreshing

Sometimes after clicking "Refresh All", not all connections can be updated successfully. At this time you need to check the following points:

• Is the data source available? For example, whether the remote server is online, whether the file has been moved or renamed
• Do I need to re-certify? Especially when connecting to an enterprise database or cloud service, a login window may pop up
• Is there any query failure due to format changes? For example, field name changes, structure changes, etc.

If a connection frequently errors occur, it is recommended to right-click the connection separately, select "Refresh" or "Edit Link" to view specific error information and process it.

Set scheduled automatic refresh

If you want the data to always remain up to date and not always refresh manually, you can enable the timed automatic refresh feature:

1. Right-click any data connection → select "Data range properties"
2. Check "Auto Refresh Every X Minutes" in the pop-up window
3. Set appropriate refresh intervals (such as every 5 minutes)

Note: This setting only takes effect when the current workbook is open, and will not continue to refresh after closing the file. In addition, if the data volume is large, refreshing too frequently may affect performance.

Use VBA to achieve more flexible refresh control (optional)

If you have higher requirements for automation, such as wanting to automatically refresh when opening a file, or trigger refresh through a button, you can use a simple VBA script:

 ThisWorkbook.RefreshAll

Put this line of code into the Open event of ThisWorkbook , and you can automatically refresh all connections when opening the file.

Basically these are the methods. Manual refresh is suitable for occasional use, automatic refresh for long-term open reports, VBA is suitable for advanced users to do customized control. It is not complicated but easy to ignore that many problems actually lie in the state of the connection itself, rather than the refresh operation itself.
