====== Dokuwiki Markdown Table Converter ======
I often seemed to be manually converting tables into markdown so I wrote a quick script to convert copy and pasted comma (or tab) seperated tables into dokuwiki table markdown.

You can try it out at this URL: https://starflyer.armchairscientist.co.uk/markdown_converter/

function copy_to_clipboard(id) {
    document.getElementById(id).select();
    document.execCommand('copy');
}
</script>
