Use this sub-skill when the task is about getting data into or out of doccano: choosing an import format, validating a file, handling encodings or MIME checks, exporting annotations, or troubleshooting task-specific dataset shapes.
Covers
- import format selection for text, sequence, seq2seq, intent, image, bounding box, segmentation, captioning, and speech projects
- export format selection and formatter behavior
- encoding, delimiter, column, and file-type validation
- relation extraction import/export handling
- collaborative vs per-user export behavior
Excludes
- project creation, labels, members, comments, and annotation CRUD: use
project-annotation
- auto-labeling template/request setup: use
auto-labeling
- install, deployment, and package build: use
setup-and-deploy
Typical path
- Confirm the project type and whether relation extraction or collaborative export is involved.
- Choose the matching file format and any delimiter or column settings.
- Validate the file contents before uploading when possible.
- Check import errors or export outputs against the documented task shape.
