Changelog

What's shipped, most recent first. We update this by hand, in order, and don't back-date entries.

• July 27, 2026

  Sign in and account dashboard

  Returning users can sign in with a passwordless email link to see their API key, usage against their plan, and manage or cancel billing — no password to remember or lose.

• July 26, 2026

  Developer API launched

  A rate-limited, authenticated /v1/convert endpoint with Free (500 requests/month) and Pro (20,000/month) tiers, self-serve API keys, and Stripe billing for upgrades.

• July 24, 2026

  Site navigation, and safer downloads

  Added a persistent top navigation bar site-wide. Excel files now only download after an explicit click — never automatically the instant a file is uploaded.

• July 22, 2026

  Contact page and expanded guide library

  Added a direct contact page, and grew the blog with additional JSON/CSV/Excel reference guides.

• July 21, 2026

  Paste JSON is now the default

  Swapped the default input tab from Upload File to Paste JSON, since most visitors arrive with JSON already in hand.

• July 18, 2026

  Sortable preview table

  The data preview shown before converting is now a real sortable table — click any column header to sort ascending or descending.

• July 16, 2026

  CSV support, dark mode, and rate limiting

  Added CSV as a second input format alongside JSON, automatic dark mode based on system preference, a request-size guard, and API-level rate limiting to keep the service reliable.

• July 16, 2026

  Full redesign and blog launch

  Redesigned the entire site on a new visual system, added SEO metadata and structured data across every page, and launched the blog.

• July 15, 2026

  Backlink credit in every export

  Every generated Excel file now includes a discreet, italic credit line crediting jsonsupport.com — visible in the spreadsheet, not just the download.

• July 14, 2026

  JSON Support launches

  Free, no-signup JSON-to-Excel conversion in the browser.
