Stuck on #N/A, #REF! or #VALUE!? This guide shows you what each Excel error means, why it appears, and how to fix it. It uses real examples with the broken formula and the fixed formula side by side.
Each of the 10 main errors gets its own chapter with:
- A plain-English explanation of what the error means.
- A list of common causes and a step-by-step fix checklist.
- 3 real examples per error (30 in total): a picture of the sample data, the broken formula with its error, and the fixed formula with the correct result.
- A tip on how to prevent the error in future.
Also included:
- A symptom finder that points you to the right chapter.
- Less common errors such as #FIELD!, #CONNECT! and #GETTING_DATA.
- 12 problems that show no error message, such as formulas showing as text, numbers stored as text and circular references.
- An error-proofing toolkit with about 14 formulas (IFERROR vs IFNA, summing while ignoring errors, counting errors).
- A debugging toolbox (Evaluate Formula, Trace Precedents, Go To Special).
- 10 broken formulas to fix, with an answer key.
- A one-page quick reference card.
