Empty cells don't have a style

Hello everyone,

I hope this is the right place to ask this. I am not quite sure if this is a bug or this is not yet implemente or I am doing something wrong.

Well to the problem: I am trying to read the style of a cell which is empty. The workbook gets loaded via this command:

 this.workbook = XLSX.readFile(path, {
            cellStyles: true
        });
  

And it also works great except that empty cells (value wise) won’t have any styles. I get it that worksheet[‘P15’].v == undefined, but why this is the case worksheet[‘P15’] == undefined.

Can you tell me if I am doing something wrong. If yes, what am I doing wrong? Or is there an alternative way to read the cell style? In my example the cell P15 has a blue background.

if(cell_ref == "P15"){
                console.log(cell_ref);
                console.log(this.currentWorksheet[cell_ref]);
            }

The output is: P15 undefined.

Thanks in advance for any assistance.

If anyone else has this particular problem. I fixed it with using the xslx-style Library. Thanks to the person who gave me the hint.

@Schmitda thanks for the report! If you pass sheetStubs:true to readFile it should generate objects for those blank cells.

@sheetjsdev sheetStubs does not appear to be consistent across formats. I made a simple sheet in Excel 2016 following the CSV:

1,2,3
4,,6
7,8,9

and bolded all 9 cells and saved in various formats. When sheetStubs is not set to true, no objects are generated. Here’s what happens when sheetStubs is set:

format	Sheets.Sheet1.B2 with sheetStubs:true
xlsb	{ t: 's', v: undefined }
xlsx	{ t: 'stub' }
xls	undefined (no object)
xml	undefined (no object)
xls5.0	undefined (no object)

recommendation: keep a separate type for stub cells, maybe call it blank
