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
.
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({
ignoreFormula:true,
ignoreStyle:true,
rowHeadersAsFrozenColumns:true,
columnHeadersAsFrozenRows:true
});
The following Visual Code sample loads an ssjson file.
