# Structured Data Files for QA

Structured Data Files (SDFs) for QA is a specific format of [SDFs](https://developers.google.com/display-video/bulk-tools/tools/sdf),
that provides the same information, but populates the data in a format that's
easier review manually.

For an overview of the format and column definitions, see the [Structured Data
Files format page and reference documentation](https://developers.google.com/display-video/api/structured-data-file/format).

## How does it work?

Structured Data Files for QA are the same as standard SDFs, but use different
column headers and a different format. For example, something that's
represented as numeric IDs in standard SDFs might be represented with a display
name in the QA format. This makes it easier to manually review the data without
reference materials.

Structured Data Files for QA are CSV files. You can review them manually in
Google Sheets or other text editing software.

Structured Data Files for QA are a subset of SDFs, and are released as part of
standard SDF versions. Up to four versions of SDFs can be released every year.
Earlier versions are regularly deprecated and usually sunset six months after
deprecation.

## What can it do?

As of v6, Structured Data Files for QA support the management of the following
resource types:

- Line Item
- YouTube Ad Group

Your team can download and manually-review these resources in bulk using
Structured Data Files for QA, by downloading and opening the resulting files.

> [!WARNING]
> **Warning:** You cannot upload SDF for QA files to create or update resources.

## Who is it built for?

Integrating with Structured Data Files for QA is ideal for teams that want to
manually review Display \& Video 360 resources in bulk for quality-assurance
purposes.

You can share and open these files offline, so multiple team members can
complete a manual review. Similar to standard SDFs, they use standardized
formatting that lets teams with engineering resources build scripts to review
the files, without the need for reference materials. Given that the data is
formatted to be more human-readable, it's also ideal for teams that don't have
the engineering resources and must review files manually.

As with standard Structured Data Files, you must occasionally migrate to a newer
version.

## What products work with it?

You can use [Structured Data Files](https://developers.google.com/display-video/bulk-tools/tools/sdf) to update resources in bulk
as needed after QA review. After you review the SDFs for QA, you can download
and edit standard SDFs based on the results of the review. Then, you can upload
the edited standard SDFs to update the resources as needed.

Similarly to standard Structured Data Files, you can use the [Display \& Video
360 API](https://developers.google.com/display-video/bulk-tools/tools/dv360-api) to programmatically generate and download
Structured Data Files for QA. Automating the download of Structured Data Files
for QA can guarantee that the necessary files are available when your team is
ready to review them.
