SBOM Validator Online

Name: SBOM Validator Online - Validate CycloneDX and SPDX Files
Author: SBOM Generator

Validate CycloneDX and SPDX SBOM files online before release, customer delivery, or CI/CD automation. Check schema compliance, required fields, Package URLs, licenses, and common best-practice issues in one workflow.

Use it for: CycloneDX validation, SPDX validation, generated SBOM review, and quick checks before sharing an inventory.

Typical workflow: generate -> validate -> fix errors -> convert if needed -> publish.

Quick Start

Paste or upload your CycloneDX or SPDX file.
Leave format on Auto-detect unless you are debugging a specific format.
Start with strict validation and best-practice checks enabled.
Review errors first, then warnings.

Which SBOM Validator Should You Use?

CycloneDX Validator

Choose CycloneDX when your SBOM comes from Syft, CycloneDX CLI, Maven, npm, Gradle, or another security-oriented generator.

SPDX Validator

Choose SPDX when your inventory is used for license review, open source disclosure, procurement, or SPDX tooling workflows.

Auto-Detect

Use auto-detect when you are unsure of the SBOM family or want to check pasted content quickly before debugging format-specific issues.

After Validation

Fix errors first, review warnings second, then use the SBOM Converter if a customer needs the file in another format.
