Angular 如何使用格式单元格导出到Excel？

使用exportAsExcelFile方法的我的Excel服务：

    public exportAsExcelFile(json: any[], excelFileName: string): void {
    const worksheet: XLSX.WorkSheet = XLSX.utils.json_to_sheet(json);
    const workbook: XLSX.WorkBook = { Sheets: { 'data': worksheet }, SheetNames: ['data'] };
    const excelBuffer: any = XLSX.write(workbook, { bookType: 'xls', type: 'array' });
    this.saveAsExcelFile(excelBuffer, excelFileName);
  }

  private saveAsExcelFile(buffer: any, fileName: string): void {
    const data: Blob = new Blob([buffer], {type: EXCEL_TYPE});
    FileSaver.saveAs(data, fileName + '_' + new  Date().getTime() + EXCEL_EXTENSION);
  }

方法为exportDataToExcel（）的我的组件：

如何使用Excel中的会计单元格格式导出json总价？

您使用的实用程序不支持开箱即用的单元格格式。你需要自己处理它，在sheetjs中潜得更深一点

您可以在单元格上迭代并相应地更改cell.z属性，因为它代表单元格格式

/* new format */
var fmt = "0.00";
/* change cell format of range B2:D4 */
var range = { s: {r:1, c:1}, e: {r:2, c:3} };
for(var R = range.s.r; R <= range.e.r; ++R) {
  for(var C = range.s.c; C <= range.e.c; ++C) {
    var cell = ws[XLSX.utils.encode_cell({r:R,c:C})];
    if(!cell || cell.t != 'n') continue; // only format numeric cells
    cell.z = fmt;
  }
}

/*新格式*/
var fmt=“0.00”；
/*更改范围B2:D4的单元格格式*/
var range={s:{r:1，c:1}，e:{r:2，c:3}；
对于（var R=范围s.R；R
/* new format */
var fmt = "0.00";
/* change cell format of range B2:D4 */
var range = { s: {r:1, c:1}, e: {r:2, c:3} };
for(var R = range.s.r; R <= range.e.r; ++R) {
  for(var C = range.s.c; C <= range.e.c; ++C) {
    var cell = ws[XLSX.utils.encode_cell({r:R,c:C})];
    if(!cell || cell.t != 'n') continue; // only format numeric cells
    cell.z = fmt;
  }
}
