These examples use the tiddler HelloThere.

Created date with no format string specified:
<<.operator-example 1 "[[HelloThere]get[created]format:date[]]">>

Created date with a format string supplied as operator parameter:
<<.operator-example 2 "[[HelloThere]get[created]format:date[DDth MMM YYYY]]">>

Modified date shown as a relative date:
<<.operator-example 3 "[[HelloThere]get[modified]format:relativedate[]]">>

Get the date and time exactly 24 hours (86,400,000 milliseconds) from now:
<<.operator-example 4 "[<now [UTC]YYYY0MM0DD0hh0mm0ss0XXX>format:date[TIMESTAMP]add[86400000]format:timestamp[DDth mmm YYYY 0hh:0mm:0ss]]">>

A tiddler title with spaces formatted as a title list:
<<.operator-example 5 """[[Hello There]format:titlelist[]]""">>

All tiddler titles tagged with <<tag TableOfContents>> formatted as a title list:
<<.operator-example 6 """[tag[TableOfContents]format:titlelist[]]""">>

A JSON string formatted as JSON – note how the JSON string is normalised to remove the duplicated properties:
<<.operator-example 7 """[[{"one":"first","one":"another","two":"second"}]format:json[]]""">>

<<.tip "To create a string to save a [[title list|Title List]] into a list field, use `format:titlelist[]` with the [[join operator|join Operator]]">>
<<.operator-example 8 """[tag[TableOfContents]format:titlelist[]join[ ]]""">>
For example, to save titles tagged `TableOfContents` to the titles field of the tiddler [[format titlelist test]]:

<$macrocall $name='wikitext-example-without-html'
src='<$button>Try it
<$action-setfield $tiddler="format titlelist test" titles={{{ [tag[TableOfContents]format:titlelist[]join[ ]] }}}/>
</$button>'/>
