StrConv Function

See Also    Example    Specifics

Returns a Variant (String) converted as specified.


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.)


The conversionargument 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.
vbFromUnicode 128 Converts the string from Unicode to the default code page of the system.

*Applies to Far East 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 for DBCS.


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