Find and Replace within a known range using typescript in the Script Editor

Hi Jrolle2022 

I'm not a JavaScript dev. and don't have access to TypeScript with my 365 subscription so can't test the following that's only my understanding after reading the doc.

The https://docs.microsoft.com/en-us/javascript/api/office-scripts/excelscript/excelscript.range?view=office-scripts has method https://docs.microsoft.com/en-us/javascript/api/office-scripts/excelscript/excelscript.range?view=office-scripts#excelscript-excelscript-range-replaceall-member(1) and after looking at the examples given for the https://docs.microsoft.com/en-us/javascript/api/office-scripts/excelscript/excelscript.replacecriteria the following should work:

function main(workbook: ExcelScript.Workbook)
{
    let sheet = workbook.getActiveWorksheet();
    let breakCol = sheet.getRange("O2:O25");
    breakCol.replaceAll("\n", ",", { completeMatch: false });
}

or, given that completeMatch defaults to false:

function main(workbook: ExcelScript.Workbook)
{
    let sheet = workbook.getActiveWorksheet();
    let breakCol = sheet.getRange("O2:O25");
    breakCol.replaceAll("\n", ",");
}

Hope this helps a bit & your feedback will be appreciated, whatever it is
