Description
Parse an ID JSON value, label null and arrays separately, and return validIdentifier only for a string or finite number.
Feature properties and foreign members are JSON metadata, distinct from the geometry coordinates. Exact key operations and ID type checks can preserve useful distinctions, but do not independently authenticate records or validate an entire Feature.
Parse an ID JSON value, label null and arrays separately, and return validIdentifier only for a string or finite number.
When to use this tool
Use Feature ID Boolean Rejection when you need a literal GeoJSON metadata, identifier, or shallow-key operation.
How to use the tool and how it works
- Enter json. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read validIdentifier, kind. Inspect validIdentifier before interpreting the associated values.

| Output field | Interpretation | Returned shape |
|---|---|---|
| validIdentifier | Whether the parsed value has an accepted identifier type. | Required. Boolean. |
| kind | Kind | Required. Text; maximum UTF-16 length 8192. |

}Limitations and assumptions
- A boolean is a successfully parsed value that returns false, rather than malformed tool input. No enclosing Feature, uniqueness, or numeric precision guarantee is checked.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Validate the complete Feature and its intended data model after editing. Preserve identifier precision and distinguish null values, absent members, collisions, and nested properties explicitly.
