Checks whether the incoming value is valid JSON text. A value passes when it is a piece of text that can be read as JSON, with correctly placed quotes, brackets, and commas. Use this when a field is expected to carry a JSON payload, for example a block of data received from another system, and you want to confirm it can be parsed before you try to read or transform it. Records that hold malformed or non-JSON text can then be routed somewhere else instead of causing errors further along.

This documentation describes: [Schema](/schemas/condition/format-json)

## Fields

This condition has no fields to configure. It checks the value it receives and answers yes or no.

## Sample data

The condition was run against a text field holding a JSON payload, with no extra settings.

| Incoming value         | Result         |
| ---------------------- | -------------- |
| `{"sku":"A1","qty":3}` | Matches        |
| `{sku: A1, qty: 3}`    | Does not match |
