Attach files stored on your computer to a sheet

You can attach almost any file from your computer to a sheet, row, or comment.

Read on to learn how to do this.

Duplicate file names

In the desktop app, when you upload a file with the same name which is already saved to the row or sheet, you’ll be prompted to select one of these options:

• Attach as a new version of the original file
• Attach as a separate file with a duplicate name

Alternatively, consider changing the name before you upload.

On the mobile app, identically named files will be uploaded directly without the option to save as a new version.

Attach files to a sheet or row

How you attach files depends on where you'd like them to be connected. You can attach files on the sheet level, or attach files directly to a specific row or comment.

To attach files at the sheet level

1. Select the Attachments icon. 
2. Select the Sheet tab. 
3. Drag any files to the Attachments pane, or select the Attach Files to Sheet button. 

Behaviors of row-level attachments

• Rows that already contain attachments will display the Attachments icon to the left of the row number.
• You can only attach files to one row at a time.
• You can't associate any already attached file with a different row or area of the sheet.

To attach files to a specific row

1. Hover your pointer over the row where you’d like to attach the file.
2. Select Attach a file to this row.
3. In the Attachments pane, select Attach Files to Row.

If you’re uploading a locally saved file, you can drag the file to the row where you want to attach it.

Attach files as you comment

1. Go to the Conversations pane. 
2. In the lower-right area of the comment box, select Attachments . 
3. Choose from where you’ll upload the file. 
4. Type your comment, and select Save.
