# Export Call Flows

Any call flow you build in Cloud Voice can be saved to a file and later brought into a different phone system. Use this when you want to reuse a design elsewhere or keep a backup outside the portal.

:::caution
Leave the exported file exactly as it is. Editing its contents can break the call flow so that it fails to load when you import it into another system.
:::

## Export a call flow

1. Sign in to the phone system portal and open **Call Flow Designer** (the area where call flows are built and managed).
2. Tick the box beside each call flow you want to save, then select **Export**. You can select one flow or several at once.

:::note
Exporting only saves a copy of the design to your computer. The call flows already set up in the portal stay in place and keep running as normal, so this is a safe action to run on a live system.
:::

## What you get

- Exporting one call flow produces a single `.json` file (JSON is a plain-text data format).
- Exporting several call flows produces a `.zip` archive. Extract (unzip) it to get the individual `.json` files inside.

:::tip
When you are ready to load a saved `.json` file into another phone system, follow [Set up a Call Flow from a JSON File](/pbx/call-flow-designer-guide/set-up-a-call-flow-from-existing-flow/#create-a-call-flow-from-existing-flow__json-file).
