# Saving and reverting
Once a Qommentary Writeback table has been setup and published to a stream, business users will start collaborating by entering and saving data.
### Saving data
To save data to the destination table (file or database), please follow these steps:
1\. Open a *Qommentary Writeback* extension
2\. Input some data
3\. Click on **Save** button
Data has been saved to the destination table:
{% hint style="warning" %}
To allow data to be saved to destination table, the extension must contain a valid connection and all fields must be valid.
{% endhint %}
### Reverting data
If you start making some changes, and wish to revert to the last state when data was saved, you can *Revert data*.
To revert data, please follow these steps:
1\. Load table with data
3\. Make some changes
4\. Click on **Revert** button
5\. Once the confirmation modal has appeared, click on the Revert button
{% hint style="success" %}
Data has been reverted successfully
{% endhint %}
