Wrapped input
Paste the full wrapped object, including header and slash.
Unwrapped output
Format and download the decoded PL/SQL.
PL/SQL developer utility
PL/SQL unwrapper for recovery, review, and migration work
UnwrapPLSQL helps developers decode wrapped PL/SQL source code from packages, package bodies, procedures, functions, triggers, and type bodies. Paste wrapped PL/SQL or upload a SQL file, then unwrap the code into readable output that can be reviewed, formatted, copied, or downloaded.
Read the UnwrapPLSQL guide to understand wrapped PL/SQL, safe usage, common recovery workflows, and how this page fits with SQL Formatter and Text Compare.
Once the code is readable, related DevToolStack pages help move the task forward: use SQL Formatter to normalize the package body, Text Compare to review two decoded versions, Regex Tester to search for grants or dependency patterns, and JSON Formatter or XML Formatter when PL/SQL code interacts with API payloads, SOAP requests, or integration configs.
Decode wrapped PL/SQL
Use the tool to inspect wrapped code when you own the source or have permission to analyze it for debugging, migration, documentation, or recovery.
Format and download SQL
After unwrapping, clean up the PL/SQL output, enable line numbers for review, copy the result, or download the decoded source as a `.sql` file.
Built for PL/SQL developers
The workflow is focused on common PL/SQL objects including wrapped package bodies, functions, procedures, and database utility code.
Example: recover a lost package body
When a repository copy is missing but a wrapped object still exists in the database, you can decode it, review the logic, and hand the readable result back into normal maintenance workflows.
Example: prepare for migration
Decode legacy PL/SQL before an upgrade or platform modernization so teams can inspect dependencies, exception blocks, dynamic SQL, and package structure more safely.
Example: compare decoded versions
After unwrapping, open SQL Formatter to normalize layout or Text Compare to review differences between two decoded packages during audits or support work.
What is wrapped PL/SQL?
Wrapped PL/SQL is obfuscated PL/SQL source code generated by database tooling to hide readable implementation details while keeping the database object executable.
Does this tool support SQL file upload?
Yes. You can upload `.sql` or `.txt` files containing wrapped PL/SQL and unwrap them directly in the browser interface.
Is unwrapping PL/SQL allowed?
Only unwrap code that you own, have permission to inspect, or are legally allowed to analyze. Do not use the tool on third-party proprietary code without authorization.
