The CycloneDX CLI tool currently supports BOM analysis, modification, diffing, merging, format conversion, signing and verification.

Conversion is supported between CycloneDX XML, JSON, Protobuf, CSV, and SPDX JSON v2.2.

Binaries can be downloaded from the releases page.

Note: The CycloneDX CLI tool is built for automation use cases. Any commands that have the --input-file option also support feeding input from stdin. Likewise, any commands that have the --output-file option support output to stdout. However, you will need to supply the input/output formats.

For example:
cat bom.json | cyclonedx-cli convert --input-format json --output-format xml > bom.xml

Convert Command

convert
  Convert between different BOM formats

Usage:
  cyclonedx convert [options]

Options:
  --input-file <input-file>                                    Input BOM filename, will read from stdin if no value provided.

Examples

Converting from XML to JSON format:
cyclonedx-cli convert --input-file sbom.xml --output-file sbom.json

Converting from XML to JSON format and piping output to additional tools:
cyclonedx-cli convert --input-file sbom.xml --output-format json | grep "somthing"

CSV Format

The CSV format is a limited representation of the list of components in a BOM.

The intention is to provide a simple way for users to produce and consume BOMs for simple use cases. Including simple data migration use cases.

The only required fields are the component name and version fields. Others can be left blank or the columns omitted.

example.csv

SPDX Format

Converting between SPDX and CycloneDX formats can result in the loss of some information. The conversion functionality is provided by the CycloneDX.Spdx.Interop library, which is part of the CycloneDX .NET library project.

For more details on what information is lost refer to the CycloneDX .NET Library project page.

Using gron for adhoc searching and analysis

gron transforms JSON into discrete assignments to make it easier to grep for what you want and see the absolute 'path' to it.

For convenience, gron is included in the CycloneDX CLI Docker image.

Example usage that lists all component names and versions

$ gron bom-1.2.json | grep -E "(components\[[[:digit:]]*\].name)|(components\[[[:digit:]]*\].version)"

json.components[0].name = "tomcat-catalina";
json.components[0].version = "9.0.14";
json.components[1].name = "mylibrary";
json.components[1].version = "1.0.0";

Or the same using an XML format BOM

$ cyclonedx convert --input-file bom.xml --output-format json | gron | grep -E "(components\[[[:digit:]]*\].name)|(components\[[[:digit:]]*\].version)"

json.components[0].name = "tomcat-catalina";
json.components[0].version = "9.0.14";
json.components[1].name = "mylibrary";
json.components[1].version = "1.0.0";

For more details on gron usage refer to the gron project page.

For more details on grep usage refer to the grep man page.

Contributing

Pull requests are welcome. But please read the CycloneDX contributing guidelines first.

To build and test the solution locally you should have .NET 6 installed. Standard commands like dotnet build and dotnet test work.

It is generally expected that pull requests will include relevant tests. Tests are automatically run on Windows, MacOS and Linux for every pull request. Build warnings will break the build.

Please let us know if you are having trouble debugging a test that is failing for a platform that you don't have access to.
