Benefits

Has a GUI-mode that exposes all options and can generate the command.

Try it

• Rename a JSON key (sandboxed)
  Use Find and Replace (fnr) to rename the JSON key 'balance' to 'accountBalance' in users.json. Because fnr's CLI operates against an entire directory matched by -dir + -fileMask (modifying files IN PLACE), the demo first copies users.json into a UUID-named sandbox subfolder under the OS temp directory, runs fnr against that sandbox, reads the modified file back into the page, then deletes both the file and the sandbox folder. The shared sample is never touched. Drop -caseSensitive or add -useRegEx to pick up partial matches; pair with -includeSubDirectories to scan a tree.

Agree to terms to run demos.
