# MID

The *MID* function returns a specified number of characters from a text string, starting at the position you specify. When used with a number, the function returns the result as text.

#### Syntax

```javascript
MID(text, position, length)
```

#### Arguments

* `text`: The text string that contains the characters to extract.
* `position`: The starting position of the characters to extract.
* `length`: The number of characters to return from the text.

#### Return value

Returns the specified number of characters from the text string.

#### Example

```javascript
MID(Product Code, 8, 4)
```

In this example, the MID function extracts 4 characters from the *Product Code* field starting at position 8 to create a shorter product code. For example, `Product0101001` returns `0101`.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fabricplan.com/documentation/plan/planning-sheets/formula-syntax/text-formatting-functions/mid.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
