+
+
+The function accept either a `Resource` created in [Hugo Pipes](/hugo-pipes/) or via [Page Bundles](content-management/page-bundles/), or simply a string. The two examples below will produce the same map:
+
+```go-html-template
+{{ $greetings := "hello = \"Hello Hugo\"" | transform.Unmarshal }}`+```
+
+```go-html-template
+{{ $greetings := "hello = \"Hello Hugo\"" | resources.FromString "data/greetings.toml" | transform.Unmarshal }}+```
+
+In both the above examples, you get a map you can work with:
+
+```go-html-template
+{{ $greetings.hello }}+```
+
+The above prints `Hello Hugo`.
+
+## CSV Options
+
+Unmarshal with CSV as input has some options you can set:
+
+comma
+: The delmiter used, default is `,`
+
+comment
+: The comment character ued in the CSV. If set, lines beginning with the comment character without preceding whitespace are ignored.:
+
+
+Example:
+
+```go-html-template
+{{ $csv := "a;b;c" | transform.Unmarshal (dict "comma" ";") }}+```
