Possible disadvantages

  • Internet Connection Required
    JSONLint is a web-based tool, so it requires an active internet connection to function, which can be a limitation in offline environments.
  • Basic Features
    While JSONLint is excellent for simple validation and formatting, it lacks more advanced features like schema validation or integration with development environments.
  • No API
    JSONLint does not offer an API for programmatic access, limiting its use in automated workflows and larger development pipelines.
  • Ads on the Website
    The website includes advertisements, which can be distracting for users and might affect the user experience.
  • Limited Customization
    The tool does not offer much in terms of customization options for how errors are displayed or how JSON is formatted, which might not meet all user needs.
  • Registry paste import
    Paste your Amazon, Zola, Babylist, The Knot, Target, or Crate & Barrel purchase list — AI extracts every giver, gift, and shared address into a card-ready list.
  • One template, personal cards

Questions & Answers

As answered by people managing JSONLint and ShipNote.

What's the story behind your product?

ShipNote's answer:

I was shocked there wasn't an easier way to write thank you notes after my wedding, so I procrastinated and built and app to do it! Allows you to ingest data from any gift registry and send a thank you postcard to all of the recipients from the registry at once. Set up a template message to start with, then ShipNote will fill in the names and gifts from the registry and you can later edit the message for each individual. Possible to send dozens of thank you notes in minutes instead of hours. ShipNote prints and mails the cards for you!

What makes your product unique?

ShipNote's answer:

ShipNote starts from your gift registry instead of a blank card. Paste your Amazon, Zola, Babylist, The Knot, Target, or Crate & Barrel purchase list and the AI turns it into a card-ready recipient list — names, gifts, and any addresses the registry shares. You write one message template, personalize a line per card, and we print, address, stamp, and mail every card the next business day. Nobody else closes the loop from "who gave what" to "card in the mailbox.

Why should a person choose your product over its competitors?

ShipNote's answer:

Speed and price for real batches. A 100-card thank-you stack takes 10–15 hours by hand; with ShipNote it's about an hour, and every card is still individually personalized. $1.99 per card on orders of 10+ — printing, addressing, and postage all included — which beats both DIY (cards plus 82¢ stamps) and the other print-and-mail services. Address verification against USPS records before anything mails, so cards actually arrive.

How would you describe the primary audience of your product?

ShipNote's answer:

Newlyweds and new parents staring down a stack of 20–100 thank-you notes after a wedding or baby shower — people who genuinely want to thank their guests but stall on the logistics: addresses scattered across registries, hand cramps, stamps, the post-office trip.

Who are some of the biggest customers of your product?

ShipNote's answer:

  • Newlywed couples working through wedding thank-you batches
  • New parents after baby showers
  • Shower hosts and families sending batches on behalf of the couple
