# ✂️Text Splitters

 As simple as this sounds, there is a lot of potential complexity here. Ideally, you want to keep the semantically related pieces of text together. What "semantically related" means could depend on the type of text. This notebook showcases several ways to do that.

**At a high level, text splitters work as following:**

1\.     Split the text up into small, semantically meaningful chunks (often sentences).

2\.     Start combining these small chunks into a larger chunk until you reach a certain size (as measured by some function).

3\.     Once you reach that size, make that chunk its own piece of text and then start creating a new chunk of text with some overlap (to keep context between chunks).

**That means there are two different axes along which you can customize your text splitter:**

1\.     How the text is split

2\.     How the chunk size is measured

#### 1)Character Text Splitter

Splits only on one type of character (defaults to "\n\n").

#### 2)Code Text Splitter

Split documents based on language-specific syntax.

#### 3)Html-To-Markdown Text Splitter

Converts Html to Markdown and then split your content into documents based on the Markdown headers.

#### 4)Markdown Text Splitter

Split your content into documents based on the Markdown headers.

#### 5)Recursive Character Text Splitter

Split documents recursively by different characters - starting with "\n\n", then "\n", then " ".

#### 6)Token Text Splitter

Splits a raw text string by first converting the text into BPE tokens, then split these tokens into chunks and convert the tokens within a single chunk back into text.

#### **7)Recursive JSON Text Splitter**

The Recursive JSON Text Splitter operates by traversing the JSON data recursively, ensuring that each chunk adheres to specified size constraints. It maintains the hierarchical structure of the JSON, which is crucial for preserving the context and relationships within the data.
