Your SUMIF formula looks right but keeps returning zero. The culprit is almost always a silent offset mismatch between the criteria range and sum range. Here's how to diagnose and fix it fast.
When Excel's OFFSET function returns #REF!, it almost always means your row or column argument has pushed the reference outside the sheet. Here's how to diagnose the root cause and fix it permanently.
If SUMPRODUCT suddenly throws #VALUE! the moment you reference a second sheet, you're not alone. This guide explains exactly why multi-sheet ranges break SUMPRODUCT and gives you working alternatives that actually produce the right totals.
SUMPRODUCT is supposed to multiply and sum your arrays in one shot, but the moment a text value sneaks in, the total goes wrong with no error to warn you. Here's exactly why it happens and how to fix it.
AVERAGEIFS returning zero instead of an error or blank is one of those silent failures that corrupt your reports without warning. Here's exactly why it happens and how to fix it cleanly.
Excel MATCH returns #N/A even when the value clearly exists in your list — and the culprit is almost always a type mismatch. Numbers stored as text look identical but behave differently. Here's how to diagnose and fix it fast.
COUNTIFS returning zero even though matching rows clearly exist? The most common culprit is mismatched criteria range sizes. Here's exactly how to diagnose and fix it in under five minutes.
XLOOKUP's approximate match modes are more nuanced than VLOOKUP's. If your formula keeps returning #N/A even though the lookup value clearly exists in a nearby range, the match mode and sort order are almost certainly the culprits.
Your INDEX MATCH formula looks right, but sorted data is feeding it wrong results. This guide breaks down the exact reason it happens and shows you the precise fix — no helper columns needed.
INDIRECT is powerful for dynamic references, but one wrong character in the sheet name and you get a #REF! error that's maddeningly hard to debug. Here's exactly what causes it and how to fix it for good.
Your Pandas read_excel call loads the file but the columns look wrong, data rows are missing, or everything shifts up by a few rows. The fix is almost always a single parameter you haven't set yet.
Every time you call DataFrame.to_excel() in a loop, only the last sheet survives. The root cause is a one-line misunderstanding of how ExcelWriter works — and the fix takes about two minutes once you know it.
