Commands:
add Add information to a BOM (currently supports files)
analyze Analyze a BOM file
convert Convert between different BOM formats

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 v2.3.
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
files
Add files to a BOM
Usage:
cyclonedx add files [options]
Options:
--input-file <input-file> Input BOM filename.
--no-input Use this option to indicate that there is no input BOM.
--output-file <output-file> Output BOM filename, will write to stdout if no value provided.
--input-format <autodetect|json|protobuf|xml> Specify input file format.
--output-format <autodetect|json|protobuf|xml> Specify output file format.
--base-path <base-path> Base path for directory to process (defaults to current working directory if omitted).
--include <include> Apache Ant style path and file patterns to specify what to include (defaults to all files, separate patterns with a space).
--exclude <exclude> Apache Ant style path and file patterns to specify what to exclude (defaults to none, separate patterns with a space).
Generating a source code BOM, excluding Git repository directory:
cyclonedx-cli add files --no-input --output-format json --exclude /.git/**
Adding build output files, from bin directory, to existing BOM:
cyclonedx-cli add files --input-file bom.json --output-format json --base-path bin
analyze
Analyze a BOM file
Usage:
cyclonedx analyze [options]
Options:
--input-file <input-file> Input BOM filename, will read from stdin if no value provided.
--input-format <autodetect|json|protobuf|xml> Specify input file format.
--output-format <json|text> Specify output format (defaults to text).
--multiple-component-versions Report components that have multiple versions in use.
Reporting on components that are included multiple times with different versions:
cyclonedx-cli analyze --input-file sbom.xml --multiple-component-versions
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.
--output-file <output-file> Output BOM filename, will write to stdout if no value provided.
--input-format <autodetect|csv|json|protobuf|spdxjson|xml> Specify input file format.
--output-format <autodetect|csv|json|protobuf|spdxjson|xml> Specify output file format.
--output-version <v1_0|v1_1|v1_2|v1_3|v1_4|v1_5|v1_6|v1_7> Specify output BOM specification version. (ignored for CSV and SPDX formats)
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"
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.
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.
diff

The CycloneDX CLI tool can also be run using docker docker run cyclonedx/cyclonedx-cli.
For Linux and MacOS, the CLI can be installed via the CycloneDX Homebrew tap:
brew install cyclonedx/cyclonedx/cyclonedx-cli
Officially supported builds are available for these platforms:
Community supported builds are available for these platforms:
.NET Core runtime dependencies are required.
For Windows these should be preinstalled.
For Ubuntu these are libc6 libgcc1 libgssapi-krb5-2 libicu66 libssl1.1 libstdc++6 zlib1g.
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";

Pull requests are welcome. But please read the CycloneDX contributing guidelines first.
To build and test the solution locally you should have .NET 8
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.
