# MrzJsonExportParams Object (IMrzJsonExportParams Interface)

This object provides functionality for tuning parameters of the captured machine-readable zone (MRZ) export to JSON format by means of ABBYY FineReader Engine export functions. A pointer to this object is passed into the export methods as an input parameter, and thus affects the results of export. All properties of a newly created object of this type are set to reasonable defaults. For more information about the default value of this or that property, see the description of the corresponding property.

The resulting file format is described in [JSON file for MRZ](/fine-reader/engine/specifications/export-formats/json-file-for-mrz).

This property is FALSE by default, which means that the coordinates are defined on an image used for capture. |

## Output parameter

This object is the output parameter of the [CreateMrzJsonExportParams](/fine-reader/engine/api-reference/engine-object-iengine-interface/creation-methods/createlessobjectgreater-methods) method of the [Engine](/fine-reader/engine/api-reference/engine-object-iengine-interface) object.

## Input parameter

This object is passed as an input parameter to the [ExportToFileEx](/fine-reader/engine/api-reference/document-related-objects/mrzdata/exporttofileex-method) method of the [MrzData](/fine-reader/engine/api-reference/document-related-objects/mrzdata) object.
