Description

Aspose get wrong json content result when save a xlsx as json format.

Env

  • Windows 10 .NET 4.7
  • Aspose.Cells for .NET 22.12

Q1

Json’s structure is not consistent when a xlsx file has only one sheet and the other xlsx file has two sheets.

  • Only one sheet output (Array):
[{....},{....},{....}]
  • Two or more sheets output (Object):
{"Sheet1":[{...},{...}], "Sheet2":[{...},{...}]}
  • Both of them expected result should be (keep the json structure is consistent):
{"Sheet1":[{...},{...}]}
{"Sheet1":[{...},{...}], "Sheet2":[{...},{...}]}

Code:

    for (var i = 1; i <= 2; i++)
    {
        var doc = new Aspose.Cells.Workbook(@"C:\Users\XCL\Desktop\test\" + i + ".xlsx");
        var ops = new Aspose.Cells.JsonSaveOptions();
        ops.ExportNestedStructure = true;
        doc.Save(@"C:\Users\XCL\Desktop\test\" + i + ".json", ops);
    }

    ops.ExportNestedStructure = true;
    doc.Save(@"C:\Users\XCL\Desktop\test\1.json", ops);

@xxtears,

This is by design. If the workbook has one (only) worksheet, then we will not render sheet name in the output JSON.

I reproduced the issue as you mentioned by using your sample file. I noticed JSON’s value is missing when a sheet is empty in the workbook. I have logged a ticket with an id “CELLSNET-52499” for your issue. We will look into it soon.

We will look into the details of your mentioned issues. Once we have an update on any of the issues, we will let you know.

For Q1, we will add JsonSaveOptions.AlwaysExportAsJsonObject property to support your needs in the next release version 23.1 with the following codes:

Workbook workbook = new Workbook( "CellsNet52502.xlsx");
JsonSaveOptions saveOptions = new JsonSaveOptions();
saveOptions.AlwaysExportAsJsonObject = true;
saveOptions.ExportNestedStructure = true;
workbook.Save(Constants.destPath + "CellsNet52502.json", saveOptions);
