Or you could try this Windows tool Find And Replace Tool I found while searching for a graphical tool to do a similar thing. I have also tried GNU Emacs (which has a Windows version) with an 18 MB JSON file and this also seemed to work fine, but again, you may find it unintuitive if you haven't used it before, but it should have a menu bar with most of the things you need.Īnother option would be to use the tool sed from Unix, of which there are Windows ports available, which is a command-line tool which can be used like: sed 's/initialstring/replacementstring/g' bigfile.json > newfile.json You may find the gVim menu has everything you need in there for find + replace and saving files. JSON validator is also one of its free tools that can be used by anyone around the globe. All of these tools provide the best quality service and 100 accurate results.

Once you are done, type :w and hit enter. SmallSEOTools is the number 1 platform that is providing hundreds of SEO and web tools without charging a penny.

Note that typing characters such as the : character doesn't edit your text since Vim is a modal editor.To replace text, type a colon : while in the editor, then type %s/initialstring/replacementstring/g and press enter.

If you want to try Vim, you might try installing it via the Windows installer from the website, and running ' gVim', which is a version of Vim with a graphical toolbar. However if you haven't used Vim before, you may find it a struggle to do what you need with it without a learning curve. The editor Vim should work on Windows, and testing it on Linux, it opens an 18 MB JSON file without issue.
