The Problem
Password confirmation looks simple, but it is one of those tasks where tiny differences matter. A single changed letter, a hidden trailing space, or the wrong case can make two entries look similar while still being wrong.
That is why a quick visual check is not enough. People can miss a lowercase letter in the middle of a string, and copied values can carry invisible spacing problems. For password-style data, the worksheet needs to be strict instead of forgiving, because close enough is still not a match.
The flow below shows the real issue. Two fields may look almost identical, but the row should only pass when every character is exactly the same.
The Problem: Exact Password Confirmation Similar-looking entries should not pass unless every character and case matches.
In this workbook, each registration row has a password entry and a confirmation entry. The challenge is to create a strict match status for each row, then complete the audit section so the sheet shows how many records were checked and how many pairs truly matched.
- Case differences should count as mismatches.
- Extra spaces should not be ignored in the strict password check.
- The summary should count the final true matches.
That keeps the sheet honest. It does not try to fix the passwords or guess user intent; it simply reports whether the two submitted values are identical.
How We Solve It
For password-style text, the safest option is EXACT. It compares two values character by character and keeps uppercase and lowercase letters separate. That makes it a better fit than a normal equals sign.
Method 1: EXACT for the strict check
Method 1: Use EXACT for a strict case-sensitive comparison.
This is the method the validator expects. If both cells match exactly, EXACT returns TRUE. If even one character is different, it returns FALSE. That is exactly the behavior we want for passwords, access codes, and other case-sensitive values.
This solves the problem because the worksheet needs a strict answer, not a close-enough one. A password only counts as matching when every character and every letter case is the same, so EXACT gives the right kind of check for column C.
=EXACT(A2, B2)
Method 2: Clean the text first with TRIM
Method 2: Remove extra spaces before comparing two text values.
Sometimes the mismatch is not a real typo. A user may copy a value with an extra space at the end, and then the comparison fails for a reason they cannot see. TRIM removes leading and trailing extra spaces, which is useful in forms where spacing problems happen a lot.
This solves a different version of the problem, where the text itself is right but the input is messy. It is helpful for general form cleanup, although it is looser than the rule we want for true password confirmation.
=TRIM(A2)=TRIM(B2)
Method 3: When a basic equals check is enough
Method 3: A regular equals check works for low-stakes text, but not for passwords.
The plain equals operator is fine for values where case does not matter, such as category labels or repeated names. It is not a good substitute here because passwords usually depend on exact casing. That difference is the whole point of this exercise.
This explains why a basic comparison does not solve the challenge well enough. It can look correct in simpler worksheets, but here it misses the security rule that uppercase and lowercase letters should not be treated as the same.
=A2=B2
Function Explanation
1. EXACT
EXACT compares two text strings and returns TRUE only when they are identical. It does not ignore case, which makes it the right tool for this challenge.
That strict behavior is the point. A normal comparison can be too soft for password-style data, but EXACT treats the row like a real confirmation check.

2. TRIM
TRIM cleans extra spaces from text. It is helpful when the issue is messy input rather than a true content mismatch.
For this exact challenge, we do not use it in the final answer because the password check should stay strict. It is still useful to understand when building friendlier cleanup sheets.

3. COUNTIF
COUNTIF finishes the audit by counting how many results in column C are TRUE. Once the row checks are done, it gives us the final total in one short formula.
That turns the strict row-by-row comparison into a simple registration audit, so the reviewer can see both the individual failures and the final match count.
A useful habit is to decide how strict your comparison should be before you build the sheet. For passwords, strict is better. For names or labels, a softer comparison may be fine.
Compare each password entry with its confirmation using a case-sensitive formula in C2:C6, then finish the summary so the audit shows how many rows were checked and how many pairs truly match.
