# Preview Changes

When there are a lot of changes to the table, it can be difficult to track and confirm them before saving them to the database. PowerTable allows you to preview all changes made to the table at once and save or discard them as needed.

{% hint style="info" %}
Previewing changes is different from the audit log. 

The [audit log](broken://pages/Qurv5UQ3JnbbDkGCbBHb) provides a comprehensive list of all changes saved to the database, whereas this menu displays changes that have not yet been saved.
{% endhint %}

1. The menu bar section on the right displays the total number of changes made to the table.

2. Upon **clicking**, it displays the list of changes, along with the type of changes. You can view all changes by clicking **All**, or select the required tab to view records with a specific type of change.

3. You can click on **Save** to save the changes to the database.

4. The preview screen also allows you to reset the changes you have made. Click on the row that you want to reset and choose **Reset.**

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.powertable.com/explore-powertable/working-with-powertable/basic-table-operations/preview-changes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
