String Replacer

By Tension Software

Open the Mac App Store to buy and download apps.


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.

String replacer 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.

Customer Reviews

Did exactly what I wanted.

Used this application to quickly find and replace token strings in 190 files. The application worked perfectly and replaced all the strings correctly. The interface is simple to use: 1) identify what files you want to validate, 2) Identify the type of file extensions you want to validate, 3) identify the text you want to replace. Thats it. With this information the application quickly searches all files and replaces the necessary text accordingly.

Simple but powerful

Simple to use but I love that it allows you to specify multiple folder trees to operate on. Search and replace plain text or use grep functions. I’ve used several similar tools over the years, and this one is the best I’ve found.
