1. Reauthorize the Excel Integration
Often, the connection between our dashboard and Microsoft needs a "handshake" refresh to maintain security permissions.
Find the M365v2 integration and click Reauthorize
2. Check the Source Status
If the settings above are correct, there may be a deeper connection error.
Open the Excel app and go to the Source tab
Look at the "Source is pushing data" field:
✅ Green Checkmark: The connection is healthy. Double-check your data range in Step 3.
❌ Red X: There is a connection failure between Valotalive and Microsoft Excel Online
Also check:
Latest content timestamp — does it match the actual time your data was last updated? Note that there may be a slight sync delay between Valotalive and Excel Online
Current data — this field is always empty for Excel Online for security reasons
💡 Tip: Make a small change to the app settings and save. This triggers a content refresh and pushes the latest data to your displays.
3. Verify the correct Excel file is selected
The link to the file can break if the file was moved or renamed in OneDrive or SharePoint.
Go to Apps and open your Excel App
Go to the Configuration tab.
Use the Microsoft File Picker to re-select the correct spreadsheet.
Note! You can only do this for apps you own. Check the app owner under the Information tab.
4. Check your Data Range and Sheet Name
A mismatch in the data range settings is the most common cause of empty pages.
Required format:
SheetName!TopLeft:BottomRightin A1 notationDefault range:
A1:Z24(first 24 rows of the first visible sheet)
Important Requirements:
Rule | Example |
Column letters must be in CAPITALS |
