Avoiding data loss when leaving shared spreadsheets means preserving both the current data and, where possible, the history behind it — not just exporting the latest snapshot and hoping nothing important was overwritten along the way. In **Jestor**, this starts with a direct spreadsheet upload, followed by a built-in trash and history system going forward.

Shared, open-edit spreadsheets have a specific risk: someone overwrites a cell, and unless there's a version history, that prior value is simply gone.

## What makes data loss likely with shared spreadsheets

- Direct editing with no confirmation before overwriting existing data
- No built-in version history — Ctrl+Z only helps in the same session
- Accidental deletion of a row or column, sometimes unnoticed for a while
- Multiple people editing simultaneously, risking silent overwrites

## How to migrate without losing data

- Export or upload the current state of the spreadsheet as the starting dataset
- Once migrated, every change to a record is preserved in **table history**
- A **trash/recycle bin** recovers accidentally deleted records or fields
- Going forward, granular permissions reduce the risk of unauthorized overwrites

## Why Jestor fits this use case

- Migration preserves the current data as the starting point, nothing is lost in the move itself
- History and trash recovery protect against the same accidental-overwrite risk spreadsheets carry
- Permissions reduce future risk instead of leaving the data fully open, as spreadsheets often are
- Data stays exportable at any time, so there's no future lock-in risk either

| Spreadsheet risk             | Structured system protection |
| ---------------------------- | ---------------------------- |
| Overwritten cell, no history | Full table history preserved |
| Accidental deletion          | Recoverable via trash        |
