🖥️ Frontend Issue — Support Additional File Formats for “Create Sample via File”

🗣️ User Feedback

"XML may not be the best format to use going forward. Other formats (e.g., JSON) can provide more accessible and complete information from additional repositories."

🎯 Goal

Extend the “Create Sample via File” feature in the SEPIA frontend to support additional file formats beyond XML. This will enable users to upload JSON, CSV, Excel, YAML, or TOML files, which will be sent to the new backend endpoint:

POST /sample/create_with_file_upload

🧩 Implementation Details

Tasks

Extend the “Create Sample via File” form to accept multiple file types.
Validate supported file extensions client-side (.xml, .json, .csv, .xlsx, .yaml, .toml).
Automatically detect and display the uploaded file format (e.g., “Detected format: JSON”).
Include the file format (extension or MIME type) in the upload request payload.
Ensure the request uses multipart/form-data (as required by backend).
Maintain compatibility with existing XML upload flow.
Update UI text/help to list all supported formats.

Notes

The backend endpoint /sample/create_with_file_upload replaces the old /sample/create_with_xml_upload.
Ensure the file field and parameter naming match the backend OpenAPI spec.
Coordinate with backend changes that extend supported formats.

✅ Target Formats

Implementation can proceed incrementally.

🧪 Testing

Validate file selection and file type detection.
Confirm payload structure matches backend expectations.
Verify success and error messages for each supported format.
