How to Fix Google Sheets IMPORTRANGE Not Importing Data

In this tutorial, you'll learn about How to Fix Google Sheets IMPORTRANGE Not Importing Data. We cover key concepts, practical examples, and best practices.

The IMPORTRANGE function imports a range of cells from another Google Sheet into your current sheet. When it shows #REF! or "Loading..." indefinitely, the source sheet has not been accessed, permissions are missing, or the spreadsheet URL is incorrect.

The Problem

=IMPORTRANGE("https://docs.google.com/spreadsheets/d/abc123", "Sheet1!A1:C10")

Returns #REF! with the error "Array result was not expanded because it would overwrite data."

Or shows "Loading..." indefinitely with no data.

Wrong approach — retyping the formula with different quote formats.

The Fix

For permission required, click the error cell to see:

#REF! → "You need permission to access this sheet"

Click "Allow access" in the popup or use the formula with IMPORTRANGE in a simpler setup:

= IMPORTRANGE("spreadsheet_url", "range")

Enter the formula. When the cell shows #REF!, click it and press Allow access.

For source sheet deleted or moved, verify the URL opens in a browser:

Open the URL directly → check the sheet name in the formula matches
= IMPORTRANGE("url", "Sheet1!A:Z")

For wrong range name, use the exact sheet name:

Sheet names are case-sensitive: "Sheet1" not "sheet1"
Spaces matter: "My Data" not "MyData"

Expected output:

IMPORTRANGE shows imported data from the source sheet
Data updates when the source changes
No permission errors for accessible sheets

Prevention Tips

• Always open the source sheet once to establish access before using IMPORTRANGE
• Use named ranges in the source sheet for cleaner formulas
• Keep the source spreadsheet URL in a separate cell for easy formula auditing
• Share the source sheet with the same Google account you use in the target sheet
• Use QUERY wrapped around IMPORTRANGE to select specific columns: =QUERY(IMPORTRANGE(...), "select * where Col1 is not null")

Common Mistakes with sheets importrange

1. Using return to exit a function early instead of wrapping a pure value in the monad
2. Mixing let bindings with <- bindings in do notation, producing type errors
3. Overlapping type class instances that cause GHC to reject the program with ambiguous dispatch errors

These mistakes appear frequently in real-world GOOGLE code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
