How to Fix Excel on iPad Losing Data During Cloud Sync
Product
Microsoft Excel
Device & OS
iPad
Scenario
Editing Excel workbooks on an iPad with unstable connections or while multiple users are modifying the file.
Observed behavior
Workbooks become out of sync with the cloud. When a conflict occurs, choosing the 'Discard changes' option permanently removes data entered locally on the iPad.
Before you start

Ensure your iPad is connected to a stable Wi-Fi network and manually copy any unsaved critical data to a new local file before troubleshooting sync issues.

Solution 1Recommended

Make Worksheets Available Offline and Sync Manually

Enabling offline access prevents immediate sync failures and data loss when your cellular or Wi-Fi connection is unstable.

When working on a mobile network, Excel attempts to auto-sync changes in real time. If the connection drops, it can cause sync conflicts. Making the file available offline allows you to edit safely and control when the data uploads to the server.

1
Enable Offline Mode

Open the Excel app on your iPad. Locate the workbook you need to edit, tap the three dots (More options) next to the file name, and select 'Make available offline'.

2
Edit Locally

Open the file and make your changes. The app will save these changes locally on your iPad without attempting to push them over an unstable connection.

3
Sync Manually

Once you have re-established a strong and stable Wi-Fi connection, allow the synchronization to finish completely before closing the workbook.

Make Worksheets Available Offline and Sync Manually
Handling Sync Conflicts: If you are prompted with a sync conflict warning, do not tap 'Discard changes' unless you intend to completely overwrite your iPad's local edits with the older cloud version.

Frequently Asked Questions

Why does Excel on my iPad keep saying there is a sync conflict?

Sync conflicts occur when Excel cannot merge the changes made on your iPad with the current version saved in the cloud. This usually happens due to a fluctuating internet connection or if another user modified the same cells simultaneously.

How can I recover my Excel data after tapping 'Discard changes'?

Tapping 'Discard changes' replaces your local iPad edits with the server's version. Unless you have a separate local backup or can check the Version History in OneDrive for a previous state, those specific unsynced local changes are typically lost permanently.

Does making an Excel file available offline consume my iPad's storage?

Yes, when you make a file available offline, a local copy is downloaded and cached on your iPad's internal storage. However, standard Excel files are generally small and should not take up a significant amount of space.
