Excel DATEVALUE Function
Chala mitrano — today DATEVALUE. Text that looks like a date becomes a real date you can subtract and sort.
चला मित्रांनो — आज DATEVALUE. तारखेसारखा दिसणारा text खरी तारीख बनतो.
चलो दोस्तों — आज DATEVALUE. तारीख जैसा text असली तारीख बन जाता है.
Purpose
Convert a date stored as text into a real Excel date.
Return value
A date serial.
Syntax
Arguments
| Argument | Required? | Description |
|---|---|---|
date_text | Required | A date written as text, e.g. "15-Mar-2020" or "2020/03/15" (locale matters). |
Version
Excel (Windows/Mac); LibreOffice has DATEVALUE too — text patterns follow locale.
How to use — Why → What → How
Why: CSV files often arrive with dates as text (left-aligned, green corners). You cannot age text dates until you convert them. Import clean-up for Indore MIS + Toronto finance CSVs. Mixed ₹ and $. In Indian back offices and foreign sister teams, DATEVALUE shows up on leave, SLA and invoice sheets every week.
What: DATEVALUE parses date_text using your locale rules and returns a serial. Format the cell as Date. Read every argument in the table once before you type; each one changes the answer on purpose.
How — numbered steps:
- Select the result cell.
- Type =DATEVALUE(A2) where A2 holds text.
- Format as Date.
- If #VALUE!, try DATE with LEFT/MID pieces or Power Query.

In real work
Drill: convert five text dates and prove ageing works only after conversion. Import clean-up for Indore MIS + Toronto finance CSVs. Mixed ₹ and $. Classroom drill: write three brand-new DATEVALUE formulas on a blank sheet using names from your own city — if you can invent them without the page open, you own the skill. Then break one formula on purpose and watch the error; recovering from that break is half of interview readiness. Always verify with a known calendar date before trusting a long chain of date formulas. Keep a personal notebook of the one mistake you make most often with this function; review it monthly. When Excel versions differ at home and in class, write the fallback formula under the modern one in a comment cell.
