Handling Errors and Data Integrity When constructing an excel formula for counting unique values , it is crucial to account for potential errors in the source data. SUMPRODUCT then takes the reciprocal of that array—turning three occurrences into one-third—and adds them together, resulting in a clean integer representing the distinct total.
If your dataset contains errors, you may need to integrate the IFERROR function to ensure that the counting mechanism ignores the faulty cells rather than breaking the entire calculation. The COUNTIF function tallies the occurrences of each specific value, generating an array of numbers.
