# What is a Submission?

A _submission_ is created when a set of files are submitted into Hyperscience together. The system then interprets each image as a page and matches each page to a live layout in the system. Pages are grouped into a document based on the matched layout.

## Accepted file types

We support the following file types:

| File type | Notes |
|-----------|-------|
| DOC | Files are converted to PDF format and then paginated. Because of this conversion, output consistency cannot be guaranteed.<br>If possible, consider using an alternate file type. |
| DOCX | Files are converted to PDF format and then paginated. Because of this conversion, output consistency cannot be guaranteed.<br>If possible, consider using an alternate file type. |
| EML (files and their attachments) | - Supported in v38.1.8 and later<br>  <br>- You can disable the processing of files attached to EML files. For more information, see [Processing EML files' attachments](https://help.hyperscience.ai/deployment/docs/processing-eml-files-attachments). |
| HEIC |  |
| HEIF |  |
| HTM | Files are converted to PDF format and then paginated. Because of this conversion, output consistency cannot be guaranteed.<br>If possible, consider using an alternate file type. |

Encrypted files are not supported.

## Supported languages

Hyperscience supports the automation of submissions written in any of our supported languages.

For more information, see [Supported Languages](https://help.hyperscience.ai/general-information/docs/supported-languages).

## Submission statuses

A submission goes through multiple steps in Hyperscience to complete extraction and completing a step changes the status of a document.

Below is a simplified Document Processing Graph that shows the machine and manual tasks a submission can go through. It includes both Structured and Semi-structured document statuses.

For more information on the manual tasks shown in this diagram, see the article [What is Supervision?](https://help.hyperscience.ai/general-information/docs/what-is-supervision)

### Status aggregation

If pages and documents in a submission have different statuses, the earliest status in the Document Processing Graph will be shown. The same is true for pages in a document.
