Import and Export JSON

You can import data from or export data to a JSON object using the fromJSON method and toJSON method.

While importing data from a JSON object, you can set several deserialization options for custom data import. These options include ignoreStyle, ignoreFormula, frozenColumnsAsRowHeaders, frozenRowsAsColumnHeaders and doNotRecalculateAfterLoad.

While exporting data to a JSON object, you can set several serialization options for exporting custom data. These options include includeBindingSource, ignoreStyle, ignoreFormula, saveAsView, rowHeadersAsFrozenColumns, columnHeadersAsFrozenRows, includeAutoMergedCells, and saveR1C1Formula.

Note: Earlier versions of SpreadJS cannot load JSON files created with SpreadJS 3.20142.11 or later.

The following code sample shows how to export to and import from a JSON object.

workbook.fromJSON(jsonData,{
ignoreFormula:true,
ignoreStyle:true,
frozenColumnsAsRowHeaders:false,
frozenRowsAsColumnHeaders:false,
doNotRecalculateAfterLoad:true
});

workbook.toJSON({
includeBindingSource:true, 
ignoreFormula:true,
ignoreStyle:true,
saveAsView:true,
rowHeadersAsFrozenColumns:true,
columnHeadersAsFrozenRows:true
includeAutoMergedCells:true,
saveR1C1Formula:true
});

The following Visual Code sample loads an ssjson file.
