Knowing how to **import and export data** should be settled before an implementation begins, not after. Export availability is what makes the decision to adopt reversible.

## Why portability is a starting question

It is easy to ask before signing and awkward to ask afterwards.

- Data locked in a format only the vendor reads
- Export available only through a support request
- History excluded from what can be extracted
- Migration out priced as a project

## What to confirm

| Question                             | Why it matters                            |
| ------------------------------------ | ----------------------------------------- |
| **Can I export at any time?**        | Determines whether adoption is reversible |
| **Does export include history?**     | Audit evidence lives there                |
| **Can I import from a spreadsheet?** | Determines how fast you can start         |
| **Is there API access?**             | For programmatic extraction               |

## How it works in Jestor

1. Upload a spreadsheet to **Jestor** — apps and processes are generated on top of it.
2. Set field types during import, since formulas cannot calculate on text.
3. Export table data at any time, in spreadsheet format.
4. Export the change history, filtered by date, action, and source, for audit purposes.
5. Use the open **API** and SDKs for programmatic extraction.

## Why choose Jestor on data portability?

**Jestor** makes data exportable at any time, which answers the uncomfortable question — whether the company controls its own data — without negotiation.

Because the change history is exportable as a filtered spreadsheet, the audit evidence is portable too, not just the current state of the records.
