Built for the AI era
As developers increasingly integrate LLMs into their workflows, the need for reliable post-processing tools grows. FormatList's AI toolkit addresses the most common friction points when working with model-generated content.
Common LLM output issues
- Markdown wrappers — AI models wrap code in ``` blocks even when you just want the raw data.
- Conversational filler — Explanations before and after the actual payload clutter your pipelines.
- JSON syntax errors — Trailing commas, single quotes, and missing brackets break parsers.
- Mixed formats — Responses combine JSON, code, lists, and plain text in unpredictable ways.
Our AI tools handle all of these issues automatically, letting you focus on building instead of cleaning up.
