Upload files to your sandbox execution. Files are written to the working directory and can be accessed directly by filename.
File Object Schema
| Field | Type | Required | Description |
|---|---|---|---|
filename |
string | Filename (e.g., "data.csv"). If omitted, file is named by index: "0", "1", etc. | |
content |
string | ✓ | Base64-encoded file content |
Example Request
{
"language": "python",
"code": "print(open('data.csv').read())",
"input_files": [
{
"filename": "data.csv",
"content": "bmFtZSxhZ2UKQWxpY2UsMzAKQm9iLDI1"
}
]
}
Limits
- Maximum files: 10 files per execution
- Maximum total size: 10MB (decoded)
- Maximum single file: 5MB (decoded)
- Filename length: 256 characters max
File Access
Files are placed in the working directory. Access them directly:
- Python:
open('data.csv') - Node.js:
fs.readFileSync('data.csv') - Ruby:
File.read('data.csv') - Go:
os.ReadFile("data.csv")
Security
- Files are isolated per execution
- Filenames cannot contain path separators (no
/or..) - Files are deleted after execution completes
