2. Navigate to Express Tools: Go to the Express Tools menu, find the Blocks category, and select Export Attributes (using the command ATTOUT).
3. Export to a Text File: Save the exported file as a text document first, then open this file in Excel for further editing.
4. Save as Excel File: Once you’ve made the required changes, save the file again, now in Excel format.

Linking Data Within Excel Sheets

Linking Between Sheets

1. Select Target Cell: Go to the target sheet (e.g., Sheet2) and click into cell A1.
2. Utilize Paste Link: Click on the drop-down arrow for the Paste button in the Home tab, then select Paste Link. This action will automatically generate a link displaying the formula =Sheet1!.

Automating Data Links Between Sheets

1. Create a Direct Link: Type the equals sign (=) into the desired cell, then click on the source sheet to select the specific cell you want to link.
