This node is only available in applications using the sandboxed runtime
When files are passed directly to an LLM, processing is limited by the model’s own multimodal capabilities. While the Doc Extractor node can convert some file types to text for LLMs to process, its supported formats are still limited. This is where the Upload File to Sandbox node helps. Once files are uploaded, downstream Agent nodes (with Agent Mode enabled) can execute commands to install tools and run scripts in the sandbox as needed, converting files into formats LLMs can process.
Processing results depends on the model’s reasoning capability.
You can find uploaded files under Artifacts. They follow the same lifecycle rules as other artifacts. How to use:
  1. In an Upload File to Sandbox node, select a file variable (e.g., from User Input).
  2. In a downstream Agent node’s prompt, reference the sandbox_path and file_name variables so the model can locate and process the file. For example:
    The file_name variable includes the file extension (e.g., data.csv).
