1. IFERROR() Function
IFERROR() ni logical function inayotumika kubadilisha errors kwenye Excel kuwa matokeo unayotaka badala ya #DIV/0!, #N/A, #VALUE!, nk.
Syntax:
IFERROR(value, value_if_error)
value = formula au calculation unayotaka kujaribu
value_if_error = thamani unayotaka kuonyesha ikiwa formula inatoa error
2. Mfano Rahisi
Mfano 1: Kuepuka #DIV/0!
=IFERROR(A2/B2, "Error: Division by zero")
A2 = 50, B2 = 0 → “Error: Division by zero”
A2 = 50, B2 = 10 → 5
Mfano 2: Kuepuka #N/A kwenye VLOOKUP
=IFERROR(VLOOKUP(B2, Sheet2!A:B, 2, FALSE), "Not Found")
Ikiwa B2 haipo kwenye Sheet2 → “Not Found” inaonekana
Ikiwa ipo → jina linarudishwa
3. Kutumia IFERROR() na Formulas Zingine
Mfano: Kuunganisha IFERROR() na SUM/AVERAGE
=IFERROR(SUM(C2:C10)/COUNT(C2:C10), 0)
Hii inahakikisha kwamba ikiwa hakuna data au kuna error, Excel inaonyesha 0 badala ya #DIV/0!.
4. Tips Muhimu

Inafanya worksheets kuwa professional na safi.
Inaweza kuunganishwa na formulas zote za Excel kama VLOOKUP, HLOOKUP, INDEX, MATCH, SUM, na wengine.
