Get your hands on the latest version of Excel for Angular

214/5000 I am currently facing an issue in Angular where I am attempting to generate an excel file. Within the file, there is a "Day" column that is meant to display numbers 1 through 31. However, when attempting this, only the last number (31) is being printed.

dataExcel : any;
days = [1, 2, 3, 4, 5, 6, 7, 8, ... , 31];

for(let i = 0 ; i <32; i++){
  this.dataExcel = [{
    Day: this.days[i]
  }]
}

I am seeking advice on how to successfully display all numbers within the range in the excel file.

Answer №1

To avoid overwriting the existing array, it is recommended to keep adding new items (days) to your current day array. The following code snippet demonstrates how you can achieve this:

dataExcel = [];
days = [1, 2, 3, 4, 5, 6, 7, 8, ... , 31];

for(let i = 0 ; i <32; i++){
  this.dataExcel.push({
    Day: this.days[i]
  });
}

If the variables are defined within the method:

dataExcel = [];
days = [1, 2, 3, 4, 5, 6, 7, 8, ... , 31];

for(let i = 0 ; i <32; i++){
 dataExcel.push({
    Day:days[i]
  });
}
