The IMPORTRANGE function is a powerful function in Google Sheets that allows users to pull data from different spreadsheets into one sheet.

How to Fix the IMPORTRANGE Internal Error Issue in Google Sheets
Here’s our step-by-step guide on how to fix the IMPORTRANGE internal error issue.
Step 1
First, you must check if the range you are importing from is accessible by your account.

If you visit the URL and see the page above, it means that you will need to request access to this spreadsheet.
Step 2
Another issue can occur if the indicated cell reference does not exist.

For example, the formula above returns an error because the spreadsheet does not contain a sheet tab labeled ‘Sheet3’.
Step 3
Sometimes, there will be issues with the Google Sheets service. Refreshing the page may or may not help with re-evaluating the IMPORTRANGE function.
If refreshing the document does not work, you can try to convert the column letters from uppercase to lowercase.
This slight change in formula is enough to let Google Sheets reset its cache and try to import again.

Step 4
Lastly, you can try opening the document in a different browser to see if this resolves the issue.
