ChatCache supports two structured data formats for developers and analysts: JSON and CSV. JSON preserves the full conversation structure in a machine-readable format, while CSV produces a flat tabular file you can open directly in Excel or Google Sheets. Both formats are processed entirely in your browser with no data sent to any server.

​
JSON export

JSON export serializes the conversation as an array of message objects. Each object contains the speaker role and the message content, giving you a clean structure to work with in any programming language.

​
Example structure

[
  {
    "role": "user",
    "content": "Explain the difference between a list and a tuple in Python."
  },
  {
    "role": "assistant",
    "content": "A list is mutable, meaning you can change its contents after creation. A tuple is immutable — once defined, its values cannot be modified."
  }
]

​
Use cases

  • Programmatic processing — load conversations into scripts, pipelines, or applications
  • Fine-tuning datasets — use exported JSON as training data for custom models
  • Developer workflows — inspect conversation structure, filter by role, or transform content

​
Processing

JSON export runs entirely in your browser. No data leaves your device.
