Google Sheets: Fix #VALUE! Function Parameter Expects Number Error

Exact Error Message:#VALUE! Function parameter expects number values. But "text" is a text and cannot be coerced to a number.

Why This Error Occurs (Root Cause Analysis)

Mathematical functions (SUM, AVERAGE, MULTIPLY, or arithmetic operators like + or *) encountered a cell containing string text, spaces, or numbers formatted as plain text.

Step-by-Step Resolution Guide

Follow these verified steps in sequence to isolate and eliminate the error condition:

1
Highlight the column and select Format > Number > Automatic or Number (1,000.12) to clear text formatting.
2
Use the VALUE() function to convert numbers formatted as text strings back into true numbers: =VALUE(TRIM(A2)).
3
Check for hidden non-breaking spaces imported from external web pages and strip them using =SUBSTITUTE(A2, CHAR(160), "").
4
In arithmetic operations, replace operator syntax (A2 * B2) with resilient function syntax (=MULTIPLY(N(A2), N(B2))) which converts text to zero instead of erroring.

Prevention Checklist & Operational Standards

🛡️ How to Permanently Prevent Recurrence

Enforce Data Validation on numeric entry columns (Data > Data validation > Criteria: Number) to prevent team members from entering alphabetical notes in price or quantity cells.
