tayoreru kyuuyo to CSV/JSON is a Google Chrome extension developed by komitake. This extension allows users to convert the salary details HTML page from Otsuka Shokai's "tayoreru kyuuyo" into CSV or JSON format for easy downloading.

When opening the extension, the extension button does not appear in a new window, so it is necessary to use a tab within the browser window, such as One Window. The extension ensures that all values, even those without data, are included in the output. Users can further process the data as needed.

It's important to note that the extension does not perform any character encoding conversion, so the CSV file will be outputted in UTF-8 format.
