Corporate datasets mein text extraction aur data quality cleaning ke primary rules.
=LEFT(text, [num_chars])
// =LEFT("EXCEL365", 5) --> "EXCEL"
// =LEFT("EMP-1025", 3) --> "EMP"
// =LEFT("LAP-2026-01", 3)--> "LAP"
=RIGHT(text, [num_chars])
// =RIGHT("EXCEL365", 3) --> "365"
// =RIGHT("EMP-1025", 4) --> "1025"
=MID(text, start_num, num_chars)
// =MID("EXCEL365", 3, 3) --> "CEL"
// =MID("EMP-1025", 5, 4) --> "1025"
[!IMPORTANT] Excel mein character indexing hamesha 1 se start hoti hai, 0 se nahi!
Total characters count karta hai (spaces aur symbols include hote hain):
=LEN("EXCEL") --> 5
=LEN("OM PRAKASH") --> 10 (OM = 2, Space = 1, PRAKASH = 7)
Data Quality Rule:
=IF(LEN(A2) = 8, "Valid Employee ID", "Check Length")
=TRIM(text): Ordinary spaces (ASCII 32) ke leading, trailing aur repeated spaces ko single space mein convert karta hai.=TRIM(CLEAN(SUBSTITUTE(A1, CHAR(160), " ")))
LAP-2026-001 se category code =LEFT(A2, 3) aur serial number =RIGHT(A2, 3) extract karein. om prakash ko =TRIM(SUBSTITUTE(A2, CHAR(160), " ")) se sanitize karein.Practice live Excel formulas directly in your browser. Real calculation verified by HyperFormula.
