JSON Word Counter

What is JSON Word Counter?

JSON Word Counter is a free online tool that quickly analyzes your JSON localization files, showing the number of string keys, translatable words, and other useful metrics to help you estimate the required translation effort and costs.

How does JSON Word Counter work?

JSON Word Counter is very easy to use. Simply drag and drop your JSON localization files into the designated area, and that’s it. Your metrics will be calculated and displayed immediately below.

What types of JSON files are supported?

JSON Word Counter currently supports only flat JSON localization files. See the example below:

{
  "common.ok": "OK",
  "page.home.title": "Home",
  ...
}

How are my JSON files processed?

Your JSON files are processed entirely in your browser. We do not upload, store, or transmit them to any external servers.

How can I use this translation word counter to calculate translation costs?

To estimate your translation costs, take the number of words or characters shown by this tool and multiply it by the rate you agreed upon with your translation agency or translator.

Note that for some languages, such as Chinese, Japanese, and Korean, translation costs are often calculated per character rather than per word, due to differences in their writing systems.
