# JsonExportParams Object (IJsonExportParams Interface)

This object provides functionality for tuning parameters of recognized text export in JSON format. 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.

You can find the JSON schema in the ABBYY\_Scheme\_JSON.json file. This file is located in the [Headers](/fine-reader/engine/distribution/distribution-macos/distribution-kit-macos) folder for macOS or the Inc folder for [Linux](/fine-reader/engine/distribution/distribution-linux/distribution-kit-linux#inc) and [Windows](/fine-reader/engine/distribution/distribution-windows/distribution-kit#inc) (Start > Programs > ABBYY FineReader Engine 12 > Installation Folders > Include Files Folder). For the description of JSON keys see the [JSON Schema Description](/fine-reader/engine/specifications/export-formats/json-schema-description).

The JsonExportParams object is a persistent object. This means that the object's current state can be written to persistent storage. Later, the object can be re-created by reading the object's state from the persistent storage. The following methods provide persistence of the object:

Linux: [SaveToFile](/fine-reader/engine/api-reference/supplementary-objects-and-methods/savetofile-method), and [LoadFromFile](/fine-reader/engine/api-reference/supplementary-objects-and-methods/loadfromfile-method)

Windows [SaveToFile](/fine-reader/engine/api-reference/supplementary-objects-and-methods/savetofile-method), [LoadFromFile](/fine-reader/engine/api-reference/supplementary-objects-and-methods/loadfromfile-method), [SaveToMemory](/fine-reader/engine/api-reference/supplementary-objects-and-methods/savetomemory-method), and [LoadFromMemory](/fine-reader/engine/api-reference/supplementary-objects-and-methods/loadfrommemory-method).
