MID ( value , startFrom {, numChars} )

Paramètre	Type	Description

startFrom	Numérique	Number designating the first character to extract in text
numChars	Numérique	Number of characters to return

Description

The MID function returns the requested number of characters from value starting at the position specified in startFrom. It accepts text data for value and numeric data for startFrom and numChars. It returns text data.

In value, pass the text string containing the characters you want to extract. It can be a string, a formula that returns a string, or a reference to a cell containing a string.

In startFrom, pass a number representing the first character you want to extract in text, with the first character in the text having a value of one (1); if not an integer, the number is truncated. It can be a string, a formula that returns a string, or a reference to a cell containing a string. If startFrom:

is greater than the length of value, an empty string (" ") is returned
is less than the length of value, but startFrom + numChars exceeds the length of value, the characters up to the end of text are returned.

In numChars, pass the number of characters to return from value; if an integer is not specified, the number is truncated.

Exemple

MID(B17,5,8)

MID("hello world",7,20) //"world"
