You can upload spreadsheet files to Runable and view them in an interactive grid in the side panel. The viewer supports editing, so you can update data, insert rows, and rearrange content without downloading the file first.

​
How to upload a spreadsheet

1

Start a conversation in Agent Mode

Spreadsheet viewing requires Agent Mode. The viewer is not available in Chat Mode.
2

Attach your file

Click the + button in the input bar and select your spreadsheet file. You can also drag and drop the file onto the input area.
3

Send your message

Add any instructions in the input bar, such as “Open this spreadsheet” or “Analyze this data.” The agent processes the file and renders it as an interactive grid in the side panel.

​
Supported file formats

FormatExtension
Excel (modern).xlsx
Excel (legacy).xls
OpenDocument.ods
Comma-separated values.csv
Tab-separated values.tsv
If a .xls or .ods file does not parse on the first attempt, Runable automatically retries with a fallback parser to maximize compatibility.

​
Viewing your spreadsheet

Once uploaded, your spreadsheet opens in the side panel as an interactive grid. You can:
  • Scroll horizontally and vertically through your data.
  • Switch between sheets if the workbook has multiple tabs.
  • Click any cell to see its contents.
A compact thumbnail preview also appears inline in the chat with quick actions to download, open the full preview, or toggle editing.

​
Editing your spreadsheet

Click the Edit button in the toolbar above the grid to enable edit mode. In edit mode you can:
ActionHow it works
Edit cell valuesClick any cell and type to change its value
Insert rowsAdd new rows to the spreadsheet
Delete rowsRemove rows you no longer need
Insert columnsAdd new columns
Delete columnsRemove columns
Move rows and columnsRearrange the order of rows or columns
Sort dataSort columns by their values
Paste dataPaste content from your clipboard into cells
Changes are saved automatically within a few seconds of each edit. Click Exit Edit when you are done to return to read-only view and prevent accidental changes.
There is no undo or version history for spreadsheet edits. Once a change is saved, it cannot be reverted. If you need to go back, use Rollback to return the conversation to a previous state.

​
What the viewer does not support

The in-browser viewer does not support everything a full desktop application does. These limitations apply to viewing and editing inside Runable only. The downloaded file retains all features.
  • You cannot execute or edit formulas. The viewer displays calculated values only.
  • You cannot apply cell formatting such as colors, borders, or fonts.
  • You cannot create or edit charts.
  • You cannot add conditional formatting.
  • You cannot merge cells.
If you need changes to formulas, charts, formatting, or structure, ask the agent in the chat. The agent can read your uploaded file and make targeted edits, including updating cells, changing formulas, adding sheets, and restyling the workbook.
