# Tutorial: Export dependency list in SBOM format **(ULTIMATE ALL)**
Dependency Scanning output can be exported to the CycloneDX JSON format.
This tutorial shows you how to generate a CycloneDX JSON SBOM for a pipeline, and then to upload it as a CI job artifact.
## Before you begin
Set up Dependency Scanning. For detailed instructions, follow [the Dependency Scanning tutorial](dependency_scanning.md).
## Create configuration files
1. Create a [snippet](../api/snippets.md) with the following code.
Filename: `export.sh`
```shell
#! /bin/sh
function create_export {
curl --silent \
--header "PRIVATE-TOKEN: $PRIVATE_TOKEN" \
-X 'POST' --data "export_type=sbom" \
"http://gitlab.example.com/api/v4/pipelines/$CI_PIPELINE_ID/dependency_list_exports" \
| jq '.id'
}
function check_status {
curl --silent \
--header "PRIVATE-TOKEN: $PRIVATE_TOKEN" \
--write-out "%{http_code}" --output /dev/null \
http://gitlab.example.com/api/v4/dependency_list_exports/$1
}
function download {
curl --header "PRIVATE-TOKEN: $PRIVATE_TOKEN" \
--output "gl-sbom-merged-$CI_PIPELINE_ID.cdx.json" \
"http://gitlab.example.com/api/v4/dependency_list_exports/$1/download"
}
function export_sbom {
local ID=$(create_export)
for run in $(seq 0 3); do
local STATUS=$(check_status $ID)
# Status is 200 when JSON is generated.
# Status is 202 when generate JSON job is running.
if [ $STATUS -eq "200" ]; then
download $ID
exit 0
elif [ $STATUS -ne "202" ]; then
exit 1
fi
echo "Waiting for JSON to be generated"
sleep 5
done
exit 1
}
export_sbom
```
The above script works in the following steps:
1. Create a CycloneDX SBOM export for the current pipeline.
1. Check the status of that export, and stop when it's ready.
1. Download the CycloneDX SBOM file.
1. Update `.gitlab-ci.yml` with the following code.
```yaml
export-merged-sbom:
before_script:
- apk add --update jq curl
stage: .post
script:
- curl --output export.sh --url "https://gitlab.example.com/api/v4/snippets/<SNIPPET_ID>/raw"
- /bin/sh export.sh
artifacts:
paths:
- "gl-sbom-merged-*.cdx.json"
```
1. Go to **Build > Pipelines** and confirm that the latest pipeline completed successfully.
In the job artifacts, `gl-sbom-merged-<pipeline_id>.cdx.json` file should be present.
