- really not acceptable for a json parses extension to inject donation pop-ups in checkout pages. used for many years, until today.
- Milos Levacic
- What a terrible decision to inject tracking code into a JSON formatter extension. Uninstalling, as I now consider this extension to be malware.
- Gary Meehan
- Disappointing to see this was injecting overlays at checkouts for me. Lost all trust. Even if intention may be good, no opt in was not cool. Open Source is hard but this move lost all trust. I suggest finding another plugin.
- Arnold Rodriguez
- Use another extension. https://x.com/wesbos/status/2039355472830939319

- Macaulay Guerin
- ANNOOOYIIING ADS EVEN THOUGH DISABLED! THEY SPY ON ME: You’re seeing this message because at some point you installed the JSON Formatter browser extension. JSON Formatter has partnered with Give Freely to bring you a free charitable donation benefit when you shop online at a partner store. This is not malware/spyware/adware; your personal information and browsing behavior is not being collected or shared/sold. As explained in the chrome store description for JSON Formatter, this popup is simply a free offer to help whichever charity you select. And you can easily opt out at any time.
- Sebastian Waschnick
- Was good, until IT FORCED AN OVERLAY for givefreely.com which was not closable. Spamware and ads, just wanted a JSON Formatter.
- Mikhail Vazhnov
- Contains some code that send requests to givefreely.com , I used it for long time but going to delete, because I expected just JSON formatter. Now I can generate similar extension using AI without strange integrations.

- Lucien Bos
- Malware injection.
- John DU HART
- Injects advertisements now, author is completely shameless.
- Andrew Benton
- This has started injecting charity donation info on checkout pages. That's absolutely unacceptable for something that's just meant to do json formatting.
- Corey Csuhta
- Inserts advertisements to donate to charity on every checkout page https://givefreely.com/charity-ad-why?p=jsonformatterprod Do not install this
- Oleg
- It showed me a pop-up on a random site when I was trying to make a purchase. This is not cool, this is intrusion and abuse of trust - the extension should format JSON, not monitor every website I visit and show pop-ups. Is it even safe? Are you trying to steal my credit card number?
- Patrick Bassner
- Super annoying advertisements added to basically every website
- Tom G
- We may get paid commissions from companies and/or affiliate programs on sites visited and/or products purchased while using this browser extension. These commissions/affiliate-payments become the donations that go to your selected charity. The popups are bs.

- It'll give a donation pop up on ecommerce checkout pages. It may or may not be legit but this is not okay for an extension to do. It's beyond agreed scope and violating trust.

- Ad injector. Into the bin.
- Dan Kleine
- Worked perfectly until now. Suddenly, I'm getting pop-ups saying that JSON Formatter is registered as an affiliate when I make purchases and that I can select donation targets. This looks like the extension is a scam now. I uninstalled it immediately. Edit: The original package is available as „JSON Formatter Classic“ now. This one here is a commercial addon now, see archived GitHub source repository.
