The JSON toolkit for developers
jsonformtable is a focused set of JSON utilities — validate, convert, share, comment on, and store JSON — all from one place. It started as a browser-only formatter and grew into a small SaaS with a public REST API, so you can use it as a backend too.
JSON Toolkit
Beautify, minify, and validate JSON instantly in the browser — with line-level error highlighting so you know exactly where it broke.
JSON ↔ Table Converter
Paste any JSON array and get an interactive table. Flip it back to JSON. Filter, sort, and export — no backend needed.
Share Links
Generate read-only share links for any JSON document. Short links support 1-hour to permanent TTLs. Large payloads are stored in R2.
Team Comments
Leave inline comments on any line of a shared JSON document. Collaborate asynchronously on API responses, fixtures, and data reviews.
REST API & Collections
Create collections, push records via API key, and query with filtering and pagination. Rate limits per plan, KV-backed for speed.
Memo Storage
Share a snapshot of your JSON data — the memo is read-only for viewers, so the original data can never be changed by accident. Great for demos and team handoffs.
AI JSON Assistant
Chat with your JSON. Ask questions, transform fields, or generate new data structures using the built-in AI assistant powered by DeepSeek.
Query Converter
Convert JSON into ready-to-use queries for Elasticsearch, MongoDB, Firebase, or cURL with one click — no manual reformatting.
Activity History
Every share, API call, and record push is logged per account. Review your full activity history and track usage from the dashboard.
Built API-first
Every feature that works in the dashboard is also available over HTTP. Authenticate with an API key — no SDK, no wrapper library, just standard REST.

Designed to stay out of your way
No telemetry dashboards, no surprise overage charges. Free tier is genuinely useful. Everything runs on Cloudflare’s edge, so latency is low wherever you are. If something breaks or feels wrong, reach out — the feedback loop is short.
