- Open a project containing at least one data file (
.csv, .tsv, .jsonl, or .parquet).
- Ensure the file is readable from the project.
- Open a supported data file from File workspace.
- Wait for the data viewer to load metadata and first rows.
- Use the view toggle to switch between Table view and Code view.
- In table view, inspect rows and filter with Filter rows.
- In code view, inspect raw content.
- Repeat for another file format to compare behavior.
.parquet currently routes to the data viewer but returns a placeholder error (Parquet support coming soon) instead of table parsing; treat it as recognized-but-not-yet-rendered.
.csv, .tsv, and .jsonl open in the data viewer and show rows.- You can switch between table and code views.
- Filtering updates visible rows in table view.
- If
.parquet is unsupported in your build, the viewer reports the limitation instead of silently failing.
- Viewer does not open
- Confirm file extension is supported by the data viewer format map.
- Rows fail to parse
- Open code view and inspect malformed delimiters or JSON lines.
- Data seems stale
- Reload the file tab, then re-open it from the file tree.
