save in excel using javascript?

Question

JavaScript

In general, I save data in excel using the function

window.open('data:application/vnd.ms-excel,' +  '5620140829152611');

Everything is saved normally, but when opening the Excel file, the number 5620140829152611 is replaced by 5620140829152610.
Any suggestions? M.b. any options need to be written in data:application/vnd.ms-excelso that all cells in excel are initially in text format?

Answer 1

You are not generating a valid Excel file, but hacking it.
In this case, no options can be passed, because they are stored in the internal structure of the file, and you have no structure.
The only way is to use another hack:

window.open('data:application/vnd.ms-excel,' +  "'5620140829152611'");
