1. ISTEXT() Function – Utangulizi
ISTEXT() hutumika kuangalia kama cell ina text.
Ikiwa cell ina text → inarudisha TRUE
Ikiwa cell ina namba, tarehe, error, blank, formula result n.k. → inarudisha FALSE
Ni function muhimu kwa:
Data validation
Text analysis
Kutengeneza IF statements
Kusafisha data (text vs numbers)
Kutambua errors za formatting
Syntax:
ISTEXT(value)
value → cell, text, au formula unayotaka ku-check.
2. Mfano Rahisi
A2 = John
A3 = 123
A4 = "123" (text)
A5 = 12/01/2025 (date)
A6 = =A2 (text from formula)
Formulas:
=ISTEXT(A2)
➡ TRUE (John ni maandishi)
=ISTEXT(A3)
➡ FALSE (123 ni namba)
=ISTEXT(A4)
➡ TRUE (inafananana na namba lakini ni text)
=ISTEXT(A5)
➡ FALSE (tarehe ni number format)
=ISTEXT(A6)
➡ TRUE (kwa sababu formula inarudisha text)
3. Kutumia ISTEXT() Ndani ya IF()
Example: Ikiwa cell ina text → andika “Maandishi”, vinginevyo → “Si Maandishi”.
=IF(ISTEXT(A2),"Maandishi","Si Maandishi")
4. ISTEXT() Pamoja na ISNUMBER()
Kutofautisha text na namba:
=IF(ISTEXT(A2),"Text",IF(ISNUMBER(A2),"Number","Other"))
Hii ni muhimu kwenye:
Imports kutoka web
CSV files
Student records
Accounting data
5. Kutumia ISTEXT() Kutambua Namba Zilizofichwa Kwenye Text
Mfano: "123 " au " 456" au "07A"
=AND(ISTEXT(A2),ISNUMBER(VALUE(A2)))
Inatambua:
Text inayofanana na namba
Zenye spaces
Zenye formatting ya web
6. ISTEXT() Kwa Filtering ya Data
Onesha rows zilizo na text pekee:
=FILTER(A2:C100,ISTEXT(A2:A100))
7. ISTEXT() Kwa Kutengeneza Validation Rules
Mfano: Ruhusu input ya text pekee:
=ISTEXT(A2)
Mfano: Ruhusu text + namba ndogo (alphanumeric):
=ISTEXT(A2)+ISNUMBER(A2)
8. ISTEXT() Haitambui:
ISTEXT() hairudishi TRUE kwa:
Namba (hata kama zimeonekana kama text lakini ni number format)
Dates
Blanks
TRUE/FALSE
Errors (#N/A, #REF!, #VALUE!)
9. ISTEXT() Pamoja na TRIM() na CLEAN()
Kwa data yenye spaces na invisible characters:
=ISTEXT(TRIM(CLEAN(A2)))
Inasafisha kwanza → halafu inapima.
10. Matumizi Muhimu ya ISTEXT()
Kutambua text vs number kwenye imported data
Kurekebisha VLOOKUP & XLOOKUP mismatches
Kutengeneza smart validation
Kutengeneza forms zinazoangalia maandishi pekee
Kusafisha data yenye namba na text zilizochanganyika
Kutengeneza conditional formatting rules
