Use case
Help Excel users repair one COUNTIFS formula where the visible problem is usually criteria syntax, mismatched criteria ranges, dates stored as text, an empty criteria cell treated as 0, a closed external workbook reference, or an unexpected zero count.
Use this page when COUNTIFS returns 0 even though matching rows seem present, returns #VALUE!, or counts the wrong rows after an import, criteria edit, copied range, date filter, or workbook-link change. Paste the formula and include at least one row that should count.
Do not hide a COUNTIFS problem with IFERROR before checking the criteria ranges and source values. A zero count may be correct, and a #VALUE! may point to a range-shape or closed-workbook issue that should be fixed directly.
A support dashboard should count open South-region tickets created in May 2026, but the formula returns 0 after the criteria were copied from another sheet.
=COUNTIFS(A2:A500,"South",C2:C500,"Open",B2:B500,">="&DATE(2026,5,1),B2:B500,"<"&DATE(2026,6,1))
Each criteria range has the same row span, text criteria are quoted, and date boundaries use DATE so Excel compares real date values instead of pasted text.
