About the Query String Parser
Values are percent-decoded, so an encoded URL inside a parameter comes back readable. A full URL is accepted as well as a bare query string.
Repeated keys are flagged, because servers disagree about which value wins - PHP takes the last, Express collects an array, and some frameworks take the first.
Questions people ask
Is your code uploaded to a server?
No. This tool runs entirely in your browser using standard web APIs, so your code never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.
Is it free, and do I need an account?
Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
