Local JSON in uploads for ACF


From ACF page:

Local JSON is a new feature added in version 5 which saves field group and field settings as .json files within your theme. The idea is similar to caching, and both dramatically speeds up ACF and allows for version control over your field settings!

This plugin require Advanced Custom Fields or Advanced Custom Fields Pro plugin to work.


  1. Upload the plugin files to the /wp-content/plugins/plugin-name directory, or install the plugin through the WordPress plugins screen directly.
  2. Activate the plugin through the ‘Plugins’ screen in WordPress
  3. Update all field groups (open group and press “Update” button)
  4. That’s all folks!
