Formulas Returning Errors

Published February 27, 2026 · Last updated March 5, 2026 · 2 min read

A formula in your sheet is showing an error instead of a result. Here's how to identify what went wrong and fix it.

Syntax errors

What you see: The cell displays an error immediately after you enter or edit a formula.

What's happening: The formula has a structural problem: a missing parenthesis, an extra comma, or it doesn't start with =. All formulas must begin with = and follow standard syntax.

How to fix it:

  1. Ensure the formula starts with =.
  2. Verify all parentheses are paired and arguments are comma-separated.
  3. Check for common issues like trailing commas or unclosed quotes.
  4. Correct and press Enter.

Example: =IF(A1>0, B1,) fails because of the trailing comma. Remove it: =IF(A1>0, B1).

Type mismatches

What you see: The formula runs but returns an unexpected result or error — a math operation shows an error, or a date calculation returns nonsense.

What's happening: The formula is trying to do something the data doesn't support. Multiplying a text field by a number, for instance, or running a SUM across cells that contain words instead of numbers.

How to fix it:

  1. Verify the data types of referenced cells match your formula's expectations (e.g., number for math, date for date calculations).
  2. Adjust field types or clean mixed data as needed.

Circular references

What you see: The formula returns an error or the cell stays blank. This happens when you save a formula that refers back to itself.

What's happening: The formula depends on its own cell, directly or indirectly. For example, Cell A1 references B1, B1 references C1, and C1 references A1. This creates an unresolvable loop.

How to fix it:

  1. Trace the formula's references to identify dependencies and any cells that point back to the formula's cell, directly or indirectly.
  2. Break the loop by adjusting references or restructuring the calculation.

Still stuck?

Ask the agent. Paste your formula and describe the expected outcome; the agent can diagnose and suggest corrections, including field name issues.
