Online services for formatting or parsing code

Hold ? Proceed with caution

We previously called out production data in test environments and now want to highlight another common practice that needs to be approached with care or even stopped entirely: online services for formatting or parsing code. There are many useful sites for formatting or parsing formats such as JSON and YAML, as well as sites that assess code tutorials or produce online code metrics. Great care is needed when using these. Pasting a block of JavaScript, JSON or similar into an unknown website can easily create security and privacy issues and might unknowingly export personal data into a different jurisdiction. These sites should never be used with production data and should be approached with caution in all other circumstances.
