The Attachment data type is a unique feature to Spreadsheet.com that lets you add files directly to cells in your worksheet. Like other data types, you can remove attached files from a cell or range of cells.
How to remove an attachment from a cell
You can quickly delete attachments by selecting the cell with the attachment and typing delete or backspace on your keyboard.
However, sometimes you want to view attachments before deleting them. In cases like these, you can select the cell with the desired attachment and open the Attachment preview menu via the breadcrumb button in the attachment cell.
In the Attachment preview menu, mouse over the attachment you wish to delete and select the Remove file button that appears.
While you can remove individual attachments one at a time from cells, you can also quickly remove multiple attachments. To remove multiple attachments, select the cells or column you wish to empty and pressing delete or backspace, or navigate to Edit and then Delete value.
How to undo
If you mistakenly deleted an attachment and have not refreshed or left the worksheet, you can recover the attachment with the undo feature. To undo a recent action, either use the keyboard shortcut Ctrl + Z, select the Undo button in the Toolbar, or choose the Undo option in the Edit menu.
