String Replacer allows to find and replace a list of strings inside files and folders on your Mac directly or in batch mode.
String Replacer allows to operate on multiple files using a multiple string couple replacement list.
It works with just a single click or using drag and drop.

String Replacer can replace strings inside any text files (text, htm, html, tsv, csv and any other file that can be opened as a text file)

It can replace in a single pass an unlimited number of strings with other strings, and parsing one or more file from a list of files and folder content (including all the files nested inside folders at any nested level)

String Replacer is document based to offer the advantage to save all the settings, the list of files and folder to precess and list of string to replace, inside the document and to have all this data ready to be used again for reuse opening the document and executing the replacing operation in batch mode, just clicking a button.

It can work also on files and folder (with nested contents) via Drag and Drop.

You just need to drop a file or a folder on the dedicated area of a target document and the dropped file (or all the files inside the dropped folder) will be processed and string replaced as specified inside the target document.

String Replacer use a simple interface in pure Mac style to edit all the strings you need to use.
In addition strings used for Find/Replace can be imported/exported from/to text files in various format for maximum flexibility in all the operations.

Fabulouse best in class utility!!!!! - Extremely easy to use yet capable of complex searches and replacements using Grep. Incredibly flexible keeping ease of use. The complexity does not get in the way of its ease of use. Very responsive developer. If you need a string replacent utility this is the one!!! You won't regret it!!!

Simple, fast, reliable - You could use terminal command to achieve the same thing however, if you care about the result and need a quick, reliable solution, get this app. We’re working with fairly large databases (100-100K string replacements trough hundreds of files) and this tool proved to be reliable. The speed is phenomenal, and the result-visualization is slowed down to human-readable (on purpose or not but it is readable). Character escaping, etc. taken care of. Tried hard but couldn’t make it fail, the only time it produced 0 replacements was when I didn’t fill the file type, assuming, it’ll run trough all files. And, I am not mentioning it as an issue, it’s actually a good idea to keep it safe. Congratulations to the developer(s), well done!
