# Change String Case Manipulator

**Mode** - set the mode:

* **Lower Case** - convert all characters to `lower case`.
* **Upper Case** - convert all characters to `UPPER CASE`.
* **Proper Case** - convert all characters to `Proper Case`. Proper case will capitalise the first letter of every word. See **Word Exclusion List** below.
* **Sentence Case** - convert all characters to `Sentence case`. **Sentence Case** will search for punctuation typically marking the end of a sentence ( `.` `!` `?` ) and capitalise the first letter of the next word. Use the **New Line as Sentence Delimiter** option if you want the first letter after a line break to be capitalised.

**Word Exclusion List** - when using the **Proper Case** mode you can add comma separated strings (words) to be excluded. For example, if the source string was `this is a string` then adding `is,a` to the **Word Exclusion List** would mean the words **is** and **a** would not be capitalised resulting in `This is a String`. By excluding words in this way you are able to create your own custom **Title Case**.

{% hint style="warning" %}
The **Word Exclusion List** is case sensitive. In the example above, if the source string was `this iS a string` then the result would be `This IS a string` because `iS` would not match the `is` entered in the list.
{% endhint %}

**New Line as Sentence Delimiter** - when checked, the first letter after a line break will be capitalised when the **Mode** is set to **Sentence Case**.
