One column of scores, another of attendance, and you are asked to flag who passes. You write the IF, type Pass without quotes, and Excel greets the entire class with #NAME?.
How to use IF Formula step by step
1. Write the first comparison
The cell to test, the operator and the value to compare with: A2 greater than or equal to 60, for instance.
2. Add a second condition if needed
With AND both must hold; with OR either is enough. The tool wraps them in the matching function.
3. Write the two results
A text, a number or a reference. Texts get their quotation marks without you typing them.
The Step Count: Traditional Friction vs. KorexTools
Writing IF by hand and debugging it (4 steps)
- Type the comparison and the two results.
- Get #NAME? because quotes are missing.
- Add AND and find it is not written between the comparisons.
- Shuffle parentheses until Excel accepts the formula.
With the KorexTools “IF Formula” builder (3 steps)
- Write the comparison.
- Add AND or OR if needed.
- Copy the IF and drag it down the column.
IF takes three arguments, and most of the errors hide in the quotation marks
IF evaluates a logical test and returns one value if it is true and another if it is false. The syntax is short, but it breaks on details: a text without quotes makes Excel read it as a name, a number inside quotes stops being a number, and a test written as IF(A2>5 AND B2<3...) does not exist, because AND is a function with its own parentheses.
The builder settles those three points. Texts are quoted, numbers and references are left as typed, and when you add a second condition both are wrapped in AND or OR inside the logical test. The result is written in the function language you prefer, with IF, SI or SE.
AND, OR or nesting several IFs: when to use which
- •Two conditions that must hold together: AND inside the logical test.
- •Two conditions where one is enough: OR inside the logical test.
- •Three or more distinct outcomes: nest another IF in the false argument or use IFS in Excel 2019 or later.
Three shapes of the IF function
| Case | Formula | Shows |
|---|---|---|
| One condition | =IF(A2>=60,"Pass","Fail") | Pass with 70 |
| With AND | =IF(AND(A2>=60,B2="Yes"),"Pass","Fail") | Pass if both |
| With OR | =IF(OR(A2>=60,B2="Yes"),"Pass","Fail") | Pass if either |
Common Mistakes and How to Avoid Them
- ⚠️Comparing a number with text that looks like a number and always getting false.
- ⚠️Typing the results with curly quotes pasted from a document.
Frequently Asked Questions
How do I put two conditions in one IF function?
Turn on the second condition and choose AND or OR. The tool writes IF(AND(...),...) or IF(OR(...),...) with the right syntax.
Can I return a cell instead of a text?
Yes. Type the reference, such as C2, in the result box and it goes in without quotes, so IF returns that cell’s content.
What if I need more than two outcomes?
This tool produces two branches. For more levels nest an IF inside the false argument, or use IFS if your Excel is 2019 or later.
How do I use the IF function with text, for example if a cell says Paid?
Pick “equals” and type the text without quotes in the comparison box: the tool adds them itself. Remember IF ignores letter case but not stray spaces at the end of the text.
How do I use the IF function with dates?
Compare the cell with another one holding a real date, or with DATE(2026,12,31). If you type the date as quoted text, Excel compares it as letters and the result can come out backwards.
Can I use the IF formula inside conditional formatting?
Yes, but without the IF. In Conditional Formatting, New Rule, “Use a formula”, paste only the comparison, for example =$B2>100: the rule paints the row when that comparison is true.
How do I combine IF with VLOOKUP or with IFERROR?
Generate each formula separately and paste one inside the other, dropping the inner equals sign. IFERROR wraps around the outside to show a notice, and VLOOKUP can sit inside the IF comparison.
