# Whalesync ID column

To enable syncing, Whalesync adds a “Whalesync ID” column to each sheet in your Google Sheets.

#### Why does Whalesync need to add a Whalesync ID column?

Unlike most apps and databases, Google Sheets doesn’t assign a unique ID to each row. To enable syncing, Whalesync adds its own ID column to uniquely identify each row.

#### Can I edit this column?

In general, you want to avoid editing this column since it is how Whalesync identifies each row. For example, this is why we suggest [avoiding sort range](/connectors/google-sheets/avoid-sort-range.md).

## 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.whalesync.com/connectors/google-sheets/whalesync-id-column.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.
