# Microsoft Excel 365

To get started with Microsoft Excel 365 spreadsheets, make sure you either sign up with a Microsoft account or [add a Microsoft authentication](/platform/contentsync.com.md#add-authentication) to your ContentSync account. 

{% hint style="info" %}
You must have at lease one Microsoft authentication enabled on your account to use Microsoft Excel 365 Spreadsheets.
{% endhint %}

## Performance

We notice that sync consistency and delays are often significant on Microsoft Excel 365 versus Google Spreadsheets. Sometimes you will need to wait a minute for Excel to be consistent before or after a sync. You may also need to refresh the Excel webpage to make sure its up to date.

## 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.contentsync.com/spreadsheets/microsoft-excel-365.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.
