Previews

The preview is the side pane that opens when you click a file in the Workbench. Use it to read a document, check a model, or verify the terminal's work without downloading anything.

Spreadsheets

Excel files and CSVs open as a full grid, with sheet tabs, frozen panes, merged cells, and embedded charts and images. A formula bar shows the formula or value of the selected cell. You can edit values directly and note cells for feedback.

Word documents

A Word document opens ready to type in. See Editing in the preview for how your changes are tracked and saved.

A Word document that can't be opened for editing shows as pages instead, with a brief notice saying so. So does a version opened from version history.

Presentations and PDFs

Presentations and PDFs open as pages, with page navigation and zoom. Your place and zoom survive refreshes. Select some text and a Send to chat button appears; see Give feedback on a file.

Everything else

Images display directly. A file that can't be previewed says so and offers a Download button instead. You can still reference these files with @; the terminal reads them normally.

Keeping previews current

A spreadsheet, presentation, or PDF refreshes on its own whenever the terminal finishes a piece of work. A brand-new file usually appears in a few seconds but can take up to a minute the first time. Press ⌥R / Alt+R to refresh one yourself at any time.

An open Word document stays on the copy you're editing, so a write by the terminal can't discard your work. Editing in the preview covers how to bring in the latest version.

A version opened from version history can't be edited.

Next steps

• Editing in the preview: change spreadsheet values and Word documents, with explicit saves.
• Give feedback on a file: send the terminal feedback tied to exact cells and pages.
• Work on a file together: what happens when teammates open the same file.
