# Manage app data

Find guides for records, fields, relationships, and calculated values.

Use the Data Editor to inspect and manage records from your connected resources. Available editing actions depend on the resource and its permissions.

Start with [Navigate the Data Editor](/user-guide/data/navigate-the-data-editor.md) to select a resource, open a collection, and arrange the grid.

## Before editing

Identify the source of truth and confirm that your account can perform the intended action. After a test edit, reopen the record and check the saved value. For connected services, also check the original source when the connector supports writes.

Hiding a field or filtering a table changes the view; it does not establish access permissions.

# 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.jetadmin.io/user-guide/data.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.
