MID, MIDB functions

This article describes the formula syntax and usage of the MID and MIDB function in Microsoft Excel.

Description

MID returns a specific number of characters from a text string, starting at the position you specify, based on the number of characters you specify.

MIDB returns a specific number of characters from a text string, starting at the position you specify, based on the number of bytes you specify.

  MID is intended for use with languages that use the single-byte character set (SBCS), whereas MIDB is intended for use with languages that use the double-byte character set (DBCS). The default language setting on your computer affects the return value in the following way:

  • MID always counts each character, whether single-byte or double-byte, as 1, no matter what the default language setting is.

  • MIDB counts each double-byte character as 2 when you have enabled the editing of a language that supports DBCS and then set it as the default language. Otherwise, MIDB counts each character as 1.

The languages that support DBCS include Japanese, Chinese (Simplified), Chinese (Traditional), and Korean.

Syntax

MID(text, start_num, num_chars)

MIDB(text, start_num, num_bytes)

The MID and MIDB function syntax has the following arguments:

  • Text    Required. The text string containing the characters you want to extract.

  • Start_num    Required. The position of the first character you want to extract in text. The first character in text has start_num 1, and so on.

  • Num_chars    Required. Specifies the number of characters you want MID to return from text.

  • Num_bytes    Required. Specifies the number of characters you want MIDB to return from text, in bytes.

Remarks

  • If start_num is greater than the length of text, MID returns "" (empty text).

  • If start_num is less than the length of text, but start_num plus num_chars exceeds the length of text, MID returns the characters up to the end of text.

  • If start_num is less than 1, MID returns the #VALUE! error value.

  • If num_chars is negative, MID returns the #VALUE! error value.

  • If num_bytes is negative, MIDB returns the #VALUE! error value.

Formula

Description

Result

=MID(A2,1,5)

Returns 5 characters from the string in A2, starting at the 1st character.

Fluid

=MID(A2,7,20)

Returns 20 characters from the string in A2, starting at the 7th character. Because the number of characters to return (20) is greater than the length of the string (10), all characters, beginning with the 7th, are returned. No empty characters (spaces) are added to the end.

Flow

=MID(A2,20,5)

Because the starting point is greater than the length (10) of the string, empty text is returned.
