# What's the CSV format for Collections?

The best format for a CSV uploaded to Collections is a single column with no column header (column A only), encoded as UTF-8.

![](https://content.gitbook.com/content/huh6w2lTUExBtn7eC56o/blobs/YCmJZEuPV0uxyaUFB8oo/Screenshot%202025%2006%2005%20at%208.35.21%20AM.png)

Only UTF-8 format is supported. Any other format will cause the upload to fail, including the Windows default in some older Excel versions.

Additional considerations

* All columns aside from column A will be ignored.
* Single empty rows will be ignored, but multiple consecutive empty rows will prevent any further content from uploading.
* Large CSVs may take some time to import.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.aiceberg.ai/inventory/what-is-the-inventory/what-are-collections/whats-the-csv-format-for-collections.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
