Importing and Exporting to JSON

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

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

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.

Earlier versions of Spread.Sheets cannot load JSON files created with SpreadJS 3.20142.11 or later.

Using Code

This example exports to and imports from a JSON object.

JavaScript	Copy Code
workbook.fromJSON(jsonData,{ ignoreFormula:true, ignoreStyle:true, frozenColumnsAsRowHeaders:false, frozenRowsAsColumnHeaders:false, doNotRecalculateAfterLoad:true }); workbook.toJSON({ ignoreFormula:true, ignoreStyle:true, rowHeadersAsFrozenColumns:true, columnHeadersAsFrozenRows:true });

JavaScript

Copy Code

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

workbook.toJSON({
ignoreFormula:true,
ignoreStyle:true,
rowHeadersAsFrozenColumns:true,
columnHeadersAsFrozenRows:true
});
