    According to your last comments you want something like this:
    txt.replace(/[^1-9_\t ]/g,'').replace(/[\t]/g,'\r');

    This will first replace everything that is not 1 to 9 or _ or space or a tab with ”, then it will replace all tabs with \r. Why did I include tabs, well the asker specifies excel data.

    Good Luck!!

    Update for your comments:

    if (txt.match(/[^1-9_\t ]/g)) {
    alert('error');
} else {
    txt=txt.replace(/[\t]/g,'\r');
}
