To format string in lower or upper case in AngularJS, we can use lowercase and uppercase filter respectively.
<div ng-app>
<div ng-init="members=[{username:'SheoNarayan', address: 'Hyderabad', salary: 500000},{username: 'Munna', address:'Scotland', salary : 659}]">
</div>
<h2>Filtered data</h2>
<ul>
<li ng-repeat="member in members">
{{member.username | uppercase}} -
{{member.address | lowercase}}
</li>
</ul>
</div>
In above code snippet, we have initialized a JSON collection using ng-init directive. Next, we are using ng-repeat to repeat the items of the JSON collection.
Notice the highlighted code, the filter uppercase for username nad lowercase for address has been used separated by "|" (pipe sign).
