--- title: "transform.Unmarshal" description: "`transform.Unmarshal` (alias `unmarshal`) parses the input and converts it into a map or an array. Supported formats are JSON, TOML, YAML and CSV." date: 2018-12-23 categories: [functions] menu: docs: parent: "functions" keywords: [] signature: ["RESOURCE or STRING | transform.Unmarshal [OPTIONS]"] hugoversion: "0.53" aliases: [] --- The function accepts 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: delimiter : The delimiter used, default is `,`. comment : The comment character used 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 "delimiter" ";") }} ```
