MID() – Extracts characters from the middle of text
The MID() function returns a specified number of characters from a text string, starting at a given position.
Syntax
MID(text, start, numChars)
- text: The text string or a cell reference containing the text from which to extract characters.
- start: The position of the first character to extract (1 = first character).
- numChars: The number of characters to extract, starting from start. Must be a non-negative integer.
Basic example
MID(T1A1, 3, 4)
Extracts 4 characters from the text in cell T1A1, starting at the 3rd character.
- If T1A1 = "Example Text": MID(T1A1, 3, 4) → "ampl"
- If T1A1 = "MathGrid": MID(T1A1, 5, 4) → "Grid"
- If T1A1 = "Data" and you request more characters than available: MID(T1A1, 2, 10) → "ata" (returns all characters from position 2 to the end)
- If T1A1 = "Information" and numChars is 0: MID(T1A1, 3, 0) → "" (an empty string)
Key features
- Middle-of-string extraction: Extracts characters from any position within the input text.
- Handling of
numChars: If numChars is 0, it returns an empty string. If numChars is greater than the remaining length of the text, it returns all characters from start to the end. - Numeric conversion: If the text argument refers to a cell containing a number, that number will first be converted to text, and then MID() will operate on that text representation.
Practical uses
- Extracting a substring such as a code, ID, or date from a longer string.
- Getting a specific part of a name or address.
- Parsing structured data where information is always in the same position.
- Isolating a section of a product or serial number.
Common mistakes
startis less than 1: The start argument must be 1 or greater (1 = first character).numCharsis negative: Providing a negative number for numChars will likely result in an error.numCharsis not a number: The numChars argument must be an integer or a cell reference pointing to one.- Text argument is a number but expecting string logic: e.g., MID(12345, 2, 2) will treat "12345" as text and return "23".
