Outputs are cleared when the input changes.
Result
Enter your data or use the example, then run the tool.
Worked example
The sample shows an OR choice with a grouped AND combination. Try GPL-2.0-only WITH Classpath-exception-2.0 for an exception node.
Method
spdx-expression-parse scans identifiers/operators and creates its actual syntax tree. The bundled license ID and exception list versions are shown. SPDX is a Linux Foundation project; no endorsement is implied.
Limits
Expression ≤5,000 characters / 100 parentheses, tree depth ≤60. Syntax/identifier checking only: no legal suitability, compatibility, compliance or license recommendation. The fixed registry may omit newer IDs and this parser is not a complete SPDX document validator.
