Push importHTML formula in a GSheets cell with Goosle Scripts - google-apps-script

Question

I'm absolutely not a dev or anything but I'm searching everywhere to make this work.
I run a swim club and I'd like the members to have a cool app to check everything about the organization. Events, calendar, best times,.. I'm currently building it with Glide and therefore I'm using GSheets as a database.
Trying to automate things a little bit, I've already managed that for every swimmer registering on the app, it creates a new line in my master worksheet with the name of the swimmer and the link to his profile on a swimming data bank website. When my script is executed, a new worksheet is created and the row with the name and the link are also appended to the right worksheet.
Well, I have two problems now.
I'd like to push an importhtml formula in a 3rd column
I'd also like that the row with the name and link in every worksheet doesn't duplicate each time the script is executed.
function createNewSheets() {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var masterSheet = spreadsheet.getSheetByName('Liste de nageurs');
// Get range with data from original sheet:
var firstRow = 1;
var firstCol = 1;
var numRows = masterSheet.getLastRow();
var numCols = masterSheet.getLastColumn();
var data_range = masterSheet.getRange(firstRow, firstCol, numRows, numCols).getValues();
// Iterate through all rows of data from Sheet1:
for (var i = 1; i < data_range.length; i++) {
var col = data_range[i]; // Current row
var swimmerName = col[0]; // swimmer name
// Get sheet with current swimmer name:
var sheet = spreadsheet.getSheetByName(swimmerName);
// Check if sheet with current swimmer name exists. If it doesn't it creates it:
if (!sheet) {
sheet = spreadsheet.insertSheet(swimmerName);
}
// Appends current row of data to the new sheet:
sheet.appendRow(col)
}
}
Can anyone help me on that one ?
It would save me a huge time to focus on other important features

Code Change:
You need to insert the formula using the setFormula() method.
// Split your data range into values and formulae:
var data_range = masterSheet.getRange(firstRow, firstCol, numRows, numCols)
var data_values = data_range.getValues();
var data_formulae = data_range.getFormulas()
for (var i = 1; i < data_values.length; i++) {
var col = data_values[i]; // Current row
var swimmerName = col[0]; // swimmer name
// Get sheet with current swimmer name:
var sheet = spreadsheet.getSheetByName(swimmerName);
// Check if sheet with current swimmer name exists. If it doesn't it creates it:
if (!sheet) {
sheet = spreadsheet.insertSheet(swimmerName);
}
// Set the first row rather than append the data:
sheet.getRange(1, 1, 1, col.length).setValues([col])
sheet.getRange(1, 3).setFormula(data_formulae[i][2])
}
