How to Fix Google Sheets QUERY Function Errors

In this tutorial, you'll learn about How to Fix Google Sheets QUERY Function Errors. We cover key concepts, practical examples, and best practices.

The QUERY function runs a SQL-like query on data in Google Sheets. When it returns #VALUE!, #N/A, or no data at all, the SQL syntax is incorrect, column references are wrong, or the data format does not match the query expectations.

The Problem

=QUERY(A1:C100, "select A, B, D where C > 100")

Returns #VALUE! — "Unable to parse query string for Function QUERY parameter 2: NO_COLUMN: D"

Or returns no rows when data clearly exists.

Wrong approach — adding quotes around column letters.

The Fix

Use column letters (A, B, C) not column names:

Wrong: =QUERY(A1:C100, "select Name, Age where City = 'NYC'")
Right: =QUERY(A1:C100, "select A, B where C = 'NYC'")

For case-insensitive text matching, use lower() or upper():

= QUERY(A1:C100, "select A, B where lower(C) contains 'nyc'")

For date comparisons, format dates as text in the query:

= QUERY(A1:C100, "select A, B where C > date '2026-01-01'")

For header rows, set the headers parameter:

= QUERY(A1:C100, "select A, B where B > 100", 1)

The third parameter (1) tells QUERY there is 1 header row.

Expected output:

QUERY returns filtered, sorted data
All rows matching the condition appear
Columns are returned in the specified order

Prevention Tips

• Use column letters (A, B, C) not column names in query strings
• Always specify the headers parameter for cleaner column references
• Wrap text values in single quotes: where A = 'text'
• Use date 'YYYY-MM-DD' format for date comparisons
• Test queries with select * first to verify data structure
• Use format clause to format dates and numbers in the output

Common Mistakes with sheets query error

1. Non-exhaustive pattern matches that compile with warnings then crash at runtime
2. Misunderstanding that String is [Char] with poor performance for large text operations
3. Using foldl instead of foldl' causing stack overflow on large lists

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.
