JsonExportSettings

Updated on Feb 19, 2026

The JsonFormatProvider exposes an ExportSettings property of type JsonExportSettings. The settings control the behavior of the JsonFormatProvider when exporting a Workbook to JSON. By adjusting the available properties you can tailor the size, richness and focus of the generated JSON payload.

Properties

Property	Type	Default	Description
ExportWhat	ExportWhat	EntireWorkbook	Portion of the workbook to export (entire workbook, active sheet, or selection).
IncludeHiddenSheets	bool	false	Include hidden worksheets when exporting the entire workbook.
IncludeDefinedNames	bool	true	Export defined names (named ranges / constants).
IncludeNumberFormats	bool	true	Emit number format codes for formatted cells.
IncludeCharts	bool	true	Serialize chart objects from exported sheets.
ChartDataMode	ChartDataMode	ReferencesOnly	Control chart data representation: only reference formulas, only resolved literal values, or both.
PrettyPrint	bool	false	Indent JSON output for readability. Disable to reduce size.
ValueRenderMode	ValueRenderMode	Display	Export raw underlying values, formatted display values, or both.
IncludeBlankCells	bool	false	Emit blank cells explicitly within the used range; otherwise they are skipped.
IncludeWorkbookProtectionFlag	bool	true	Include workbook protection state (Workbook.IsProtected).
IncludeActiveSheet	bool	true	Emit the name of the active worksheet in metadata.
SelectedRanges	List<CellRange>	empty	Ranges to export when ExportWhat is Selection. Empty collection falls back to active sheet.
IncludeChartStats	bool	true	Include min, max, average, sum, stdev and count aggregates for chart series.
IncludeChartSummaries	bool	true	Include natural language summary strings per chart.
IncludeChartTrends	bool	true	Include simple trend classification (increasing / decreasing / flat) for eligible series.

Basic Usage

The following example shows how you can create a JsonExportSettings instance with the desired settings while exporting a Workbook to JSON format:

c#

Workbook workbook;
XlsxFormatProvider xlsxFormatProvider = new XlsxFormatProvider();

using (Stream input = new FileStream("inputFile.xlsx", FileMode.Open))
{
    workbook = xlsxFormatProvider.Import(input, TimeSpan.FromSeconds(10));
}

string jsonOutputPath = "outputFile.json";
JsonFormatProvider jsonFormatProvider = new JsonFormatProvider();

JsonExportSettings jsonExportSettings = new JsonExportSettings
{
    ExportWhat = ExportWhat.EntireWorkbook,
    IncludeWorkbookProtectionFlag = true,
    IncludeNumberFormats = true,
    IncludeActiveSheet = true,
    IncludeBlankCells = true,
    ValueRenderMode = ValueRenderMode.Raw,
    PrettyPrint = true,
    IncludeHiddenSheets = true,
    ChartDataMode = ChartDataMode.ReferencesOnly,
    IncludeCharts = true,
    IncludeChartStats = true,
    IncludeChartSummaries = true,
    IncludeChartTrends = true,
    IncludeDefinedNames = true
};

jsonFormatProvider.ExportSettings = jsonExportSettings;

using (Stream output = new FileStream(jsonOutputPath, FileMode.Create))
{
    jsonFormatProvider.Export(workbook, output, TimeSpan.FromSeconds(10));
}
