Creating an External Reference in Excel

Understanding Workbook Links

Workbook links facilitate data integration from various workbooks into a single summary or report workbook. These links, essential for combining data, require both the source and destination workbooks to be stored online and accessible via a Microsoft 365 account.

Enabling Workbook Links

When opening a workbook containing formulas that link to external data, ensure that workbook links are enabled. This step is crucial for maintaining data accuracy and security, as Excel treats workbook links as potentially unsafe and will not refresh data without proper authorization.

Creating Workbook Links

To create an external reference, define a cell in the destination workbook where the link will reside. The formula used will differ based on the state of the source workbook—whether it is open or closed.

Using Hyperlinks for Quick Access

Hyperlinks in Excel provide swift access to related files. Create a hyperlink by selecting a cell, entering a description, and using the 'File...' button to locate the source workbook. Employ the 'Bookmark...' button to link directly to a specific sheet within the workbook.

Adding Descriptions to Hyperlinks

Enhance hyperlink usability by adding a screen tip description using the 'Screen Tip...' button. This description appears when users hover over the hyperlink, offering additional context or guidance.
