<p>Hi,</p>
<p> </p>
<p>You can use JavaScript String methods to parse your string. For example, if "Text" is the originating column in your data set, you can create a computed column "StrippedText" with the following expression:</p>
<pre class="_prettyXprint _lang-">
out = "";
if(row["Text"].substr(0,1) == "[") {
end = row["Text"].indexOf("]");
out = row["Text"].substring(0, end + 1);
}
out;
</pre>
<p>Hope this helps,</p>
<p> </p>
<p>P.</p>
