Version History and Snapshots

Your built-in safety net

StretchSheets protects your work with automatic version history. Every time a workbook's content is saved, StretchSheets captures a snapshot of the previous state before applying the new one. You never have to remember to make a backup — it happens on every save.

How snapshots are created

1. You edit a workbook and it's saved (via the Save button or autosave).
2. Before the new content overwrites the old, StretchSheets records the previous version as a snapshot.
3. Each snapshot stores when it was captured, who made the change (by email), and the workbook title at that time.
4. The most recent snapshots are kept — up to 20 per workbook — with the newest first. Older snapshots roll off as new ones are added.

This means the last 20 saved states of any workbook are always available as restore points.

Reviewing version history

Each workbook exposes its snapshot list, showing for every entry:

• When it was captured (timestamp).
• Who made the change (the editor's email).
• Title of the workbook at that point.
• Whether captured data is available for that entry.

The Insights view and the Dashboard also surface snapshot activity across your whole library, so you can see version history working at a glance (the Dashboard's "Snapshots" card totals them).

A realistic example

You're refining a budget and, after several rounds of edits, realize a set of figures from an hour ago was actually correct. Because every save captured a snapshot, the workbook's history holds a series of restore points from your editing session — each stamped with the time and your email. You review the list, find the snapshot from before the bad change, and use it to recover the earlier numbers, confident that nothing in the last 20 saves was lost.

Tips

• Save at meaningful milestones. Since each save creates a snapshot, saving after a completed section gives you a clean, labeled point to return to.
• The email attached to each snapshot makes history an audit trail — useful when several people edit the same workbook.
• History keeps the most recent 20 states; for long-term archival of an exact version, also export the workbook to XLSX or CSV (see Importing and Exporting Data).
• Snapshots are per workbook, so busy sheets and rarely-touched sheets each keep their own independent history.

Troubleshooting

• I don't see any snapshots yet. Snapshots begin accumulating once a workbook has been saved with changes at least once — a brand-new workbook won't have prior states.
• An old version I wanted is gone. History retains the latest 20 saves; if you've saved more than 20 times since, the oldest states have rolled off. Export important versions to preserve them beyond that window.
• "Unable to load version snapshots." Reopen the workbook and try again; if it persists, the workbook may have been deleted or you may be viewing it from the wrong organization.

FAQ

How many versions are kept?
Up to 20 snapshots per workbook, newest first.

Are snapshots created automatically?
Yes — one is captured on every content save, with no action needed from you.

Does version history record who made changes?
Yes. Each snapshot stores the editor's email and a timestamp, which also feeds the app's audit view.
