# String: Does not match wildcard pattern

> Checks that a string does not match the supplied wildcard pattern.

Passes when the incoming text does *not* fit a wildcard pattern you supply. This is the opposite of [String: Matches wildcard pattern](/references/condition/string-match): it lets you act only on values that fall outside a certain shape, for example everything whose code does not start with `SKU-`, or files that do not end in `.tmp`.

A wildcard pattern uses two special characters: `*` stands for any run of characters, including none, and `?` stands for exactly one character. Everything else has to match literally, and the comparison is case-sensitive. So with `SKU-*`, the value `PROD-5` passes this condition because it does not fit the pattern, while `SKU-1001` fails because it does fit. When you need finer control than wildcards allow, see [String: Does not match regular expression](/references/condition/string-not-regex).

This documentation describes: [Schema](/schemas/condition/string-not-match)

## Fields

<FormField property="value" label="Value" required>
  The wildcard pattern the incoming text is checked against. The condition passes when the text does *not* fit the pattern and fails when it does. Use `*` to stand for any run of characters and `?` for a single character. With a pattern of `SKU-*`, a code of `PROD-5` passes while `SKU-1001` fails.
</FormField>

## Sample data

With the pattern set to `SKU-*`, the condition checks whether a product code does *not* start with `SKU-`.

| Field | Value   |
| ----- | ------- |
| Value | `SKU-*` |

| Value      | Result         |
| ---------- | -------------- |
| `PROD-5`   | Matches        |
| `SKU-1001` | Does not match |

```json Configuration theme={null}
{
  "prototype": "string-not-match",
  "parameters": {
    "value": "SKU-*"
  }
