This is a Moodle plugin that allows administrators to search and replace strings in the Moodle database.

It is conceptually similar to the replace tool in core, but way more powerful as it can search and replace strings in tables and columns of the Moodle database, as well as inside files withing the File API, including files inside zip files such as H5P.

They can use simple text search or regular expressions, and the found records can be downloaded as csv and the per-record replacements uploaded as a new csv giving very fine grained replacement capability.
