# Output Parsers

***

Output Parser nodes are responsible for taking the output of a model and transforming it to a more suitable format for downstream tasks. Useful when you are using LLMs to generate structured data, or to normalize output from chat models and LLMs.

### Output Parser Nodes:

* [CSV Output Parser](https://docs.flowiseai.com/integrations/langchain/output-parsers/csv-output-parser)
* [Custom List Output Parser](https://docs.flowiseai.com/integrations/langchain/output-parsers/custom-list-output-parser)
* [Structured Output Parser](https://docs.flowiseai.com/integrations/langchain/output-parsers/structured-output-parser)
* [Advanced Structured Output Parser](https://docs.flowiseai.com/integrations/langchain/output-parsers/advanced-structured-output-parser)
