Data files

CSV, TSV, and JSONL files open in a table viewer with sorting, filtering, and in-cell editing.

CSV, TSV, and JSONL files open in a dedicated table viewer instead of a text editor.

View and edit

1

Open the file

Open a supported data file (.csv, .tsv, .jsonl) from the file tree.

2

Browse and filter

Use Table view to browse rows and columns, sort by clicking a column header, and filter rows with the filter input.

3

Edit

Edit a cell directly by clicking into it, or switch to Code view to see or edit the raw file content instead.

Attach a data file to the AI and ask it a question about the contents. See Using AI and the Quickstart for a worked example.

Things to know

• Parquet (.parquet) files are recognized but not yet viewable. Open in Code view, or convert to CSV or JSONL first.

• Pagination is fixed at 100 rows per page.

• Files up to 50 MB parse without warnings; the hard limit is 200 MB.

Troubleshooting

The viewer won't open

Confirm the extension is .csv, .tsv, or .jsonl.

Rows fail to parse

Switch to Code view and check for malformed delimiters or broken JSON lines.

Data looks stale

Reopen the file tab.
