StrConv Function

  • Article

This page is specific to the Visual Basic for Applications (VBA) Language Reference for Office 2010.

Returns a Variant (String) converted as specified.

Syntax

StrConv(string, conversion, LCID)

The StrConv function syntax has these named arguments:

Part

Description

string

Required. String expression to be converted.

conversion

Required. Integer. The sum of values specifying the type of conversion to perform.

LCID

Optional. The LocaleID, if different than the system LocaleID. (The system LocaleID is the default.)

Settings

The conversion argument settings are:

Constant

Value

Description

vbUpperCase

1

Converts the string to uppercase characters.

vbLowerCase

2

Converts the string to lowercase characters.

vbProperCase

3

Converts the first letter of every word in string to uppercase.

vbWide*

4*

Converts narrow (single-byte) characters in string to wide (double-byte) characters.

vbNarrow*

8*

Converts wide (double-byte) characters in string to narrow (single-byte) characters.

vbKatakana**

16**

Converts Hiragana characters in string to Katakana characters.

vbHiragana**

32**

Converts Katakana characters in string to Hiragana characters.

vbUnicode

64

Converts the string to Unicode using the default code page of the system. (Not available on the Macintosh.)

vbFromUnicode

128

Converts the string from Unicode to the default code page of the system. (Not available on the Macintosh.)

*Applies to East Asia locales.

**Applies to Japan only.

Note

These constants are specified by Visual Basic for Applications. As a result, they may be used anywhere in your code in place of the actual values. Most can be combined, for example, vbUpperCase + vbWide, except when they are mutually exclusive, for example, vbUnicode + vbFromUnicode. The constants vbWide, vbNarrow, vbKatakana, and vbHiragana cause run-time errors when used in locales where they do not apply.

The following are valid word separators for proper casing: Null (Chr$(0)), horizontal tab (Chr$(9)), linefeed (Chr$(10)), vertical tab (Chr$(11)), form feed (Chr$(12)), carriage return (Chr$(13)), space (SBCS) (Chr$(32)). The actual value for a space varies by country/region for DBCS.

Remarks

When converting from a Byte array in ANSI format to a string, use the StrConv function. When converting from such an array in Unicode format, use an assignment statement.

Example

This example uses the StrConv function to convert a Unicode string to an ANSI string.

Dim i As Long
Dim x() As Byte
x = StrConv("ABCDEFG", vbFromUnicode)    ' Convert string.
For i = 0 To UBound(x)
    Debug.Print x(i)
Next
