# Undoing an import

Syncek can undo an import within 72 hours of the run finishing: it deletes the
records the run created and gives the records it updated their earlier values
back. Go to **Settings, then Workspace, then Imports**, open the actions
menu on the run and choose **Undo Import**. Hover over its date to see when undo expires.

## What undo does

- Every record the run created is deleted.
- Every record the run updated gets back the values it had before, in the fields
  the run changed. One gap today: in each group of 500 rows, a column left empty
  in the first row that updates a record is not saved for the other rows, and undo
  empties that field on them instead of restoring it.

The confirmation shows both counts before anything happens. Undo then runs in the
background, the way the import did.

## When undo is available

Within 72 hours of the run finishing, for a run that completed and created or
updated at least one record. After 72 hours the option is gone, and Syncek can
no longer restore the earlier values for you.

## Undo early

Undo does not merge with work done since the import. A field someone edited by
hand after an update run goes back to its value from before the import, and the
edit is lost. Undo as soon as a run looks wrong, before your team starts working
on the records it touched.

To bring the data back in, [fix the file](https://syncek.com/docs/your-data/fixing-import-problems) and import it again.

## Before an update run

Undo restores only what a run changed. Unmap the columns that should not touch existing records before you start.
