About this tool

Before sharing COBOL code, you can replace unique names and values with alternative values, taking fixed-form/free-form and PIC clauses into account.

Features

  • Fixed-format and free-format common COBOL syntax
  • Masking and anonymization of program names, sections and paragraphs, data items, strings, numbers, and comments

How to use

  1. Paste the COBOL code into the input field.
  2. Select what to mask and how to handle comments.
  3. Check and copy the masking results.
  4. You can remove masking individually by right-clicking on the target area of the masking result, and reapply by right-clicking again.

Limitations

  • It does not guarantee complete parsing equivalent to the COBOL compiler.
  • If the code contains dialect-specific reserved words, COPY statements, or embedded SQL, review the result manually.
