Proper Case
Location on ribbon: Tab DVD Addin → Group Text and Number → Menu Case
Command ID: btnProperCase
What it does
Capitalizes the first letter of each word and lowercases the rest (Title Case) — like Excel's PROPER function, but applied directly to the cells so no helper column is needed. Unlike PROPER, it keeps units, marks and abbreviations intact.
This is the right style for people's names, company names and short item titles in a manpower allocation sheet, an engineering staff list or a subcontractor tracker, where entries are usually typed with mixed capitalization.
How to use
- Select the cells you want normalized.
- Go to tab DVD Addin → group Text and Number → open the Case menu → click Proper Case.
- The Confirm data change box appears before anything is overwritten; keep Back up sheet ticked and click Continue.
- The Excel status bar reports "Changed N/M cells". If nothing changed, a message box explains why.

Illustrated walkthrough
Practice
Download this command's sample workbook — the data matches the pictures below (sheet Manpower), so you can follow each step right away.
Step 1. Select the column to normalize, for example the name / company column of a site manpower list typed in mixed case (1).

Step 2. On the ribbon, open the DVD Addin tab → Text and Number group → open Case → choose Proper Case.

Step 3. The add-in asks before overwriting. Keep the sheet backup ticked (1) so that Ctrl+Z right after the command puts the sheet back, then click Continue (2).

Step 4. Every word gets an initial capital and the rest in lower case; abbreviations and codes (JSC, QA, QC, C1) are kept as typed (1). The status bar reports how many cells changed (2).

Example
The name column of a site manpower timesheet:
| Before | After |
|---|---|
| nguyen van an | Nguyen Van An |
| TRAN THI BINH | Tran Thi Binh |
| le Hoang nam | Le Hoang Nam |
| HOANG LONG CONSTRUCTION JSC | Hoang Long Construction JSC |
| HDPE pipe crew, zone C1 | HDPE Pipe Crew, Zone C1 |
Notes
- The command keeps the following exactly as typed:
- units of measure:
MPa,kN,kg,mm,m2,m3…; - marks that mix letters and digits:
C1,D12,P66,M250…; - common abbreviations:
TCVN,QCVN,UBND,BTCT,HDPE…; - in a cell that also contains lowercase text, every ALL-CAPS word of 2 or more letters (treated as an abbreviation). In a cell typed entirely in capitals, only the common abbreviations above are kept.
- units of measure:
- So a name typed in capitals inside lowercase text (for example
le hoang NAM) also staysNAM. An abbreviation typed in lowercase (for examplejsc) cannot be recognized and becomesJsc— fix it by hand or use SMART case (AI). - Formula cells are preserved — they are never overwritten with their values.
- Hold ESC while it runs to stop early; areas already written stay written.
- The selection is clamped to the UsedRange so whole-column selections are still fast, and empty cells are skipped.
- Content is overwritten in place. Ctrl+Z right after the command puts the sheet back as it was (thanks to the backup); see Restore data.
