# Serialization options

You can pass additional options in the arguments to perform text transformations.

```json
{
  "hello": "$1",
}
```

```typescript
locale.translate('hello', 'niro you are cool.yesuppercase');
// output: NIRO YOU ARE COOL
```

* <mark style="color:blue;">.yesuppercase</mark> - Returns the value of the original string converted to uppercase.
* <mark style="color:blue;">.yeslowercase</mark> - Returns the value of the original string converted to lowercase.
* <mark style="color:blue;">.yestrim</mark> - Removes the leading and trailing whitespace.
* <mark style="color:blue;">.space\[count]</mark> - Add x spaces to the end of the text.
* <mark style="color:blue;">.repeat\[count]</mark> - Repeat x times the value.

```typescript
locale.translate('hello', 'Repeat this .repeat[2]');
// output: Repeat this Repeat this
```

{
  "hello": "$1",
  "speak": "Thanks for use!",
}
