Convert CSV to Excel Office Script

// Create a 2D array with one row. change back
let data: string[][] = [];


Because I tested it in native js environment rather than type script, so I use let data=[] without type declare.
if possible,use that in your codes as above.



what I mean change the regular expression which can parse directly without additional codes to check like below
// Check for blanks at the start of the row.
if (row[0].charAt(0) === ',') {
row.unshift("");
}
