What shipped, and when.

JSON for Sheets is live

The production add-on is now publicly available from the Google Workspace Marketplace.

• Install directly from the verified Marketplace listing.
• Start with five successful remote fetches per UTC day on Free.
• Use local JSON tools without consuming the remote-fetch allowance.

Credential isolation and bounded transformations

The testable runtime now binds saved credentials to the configured API origin and rejects oversized nested-array expansion before allocating the output.

• Cross-origin redirects lose caller headers, credentials, and request bodies.
• Response-driven next-URL pagination cannot switch origins.
• Validation failures return actionable error codes instead of generic service errors.

Public product and policy website

Published the JSON for Sheets product explanation, feature reference, planned pricing, documentation, support details, privacy policy, and terms.

• Responsive, accessible pages designed for people and search crawlers.
• Public OAuth branding URLs for the homepage, privacy policy, and terms.
• Beta contact path while the add-on and Marketplace listing are being built.

API request builder and automated imports

The testable add-on now handles authenticated and paginated API workflows without putting upstream secrets in a spreadsheet.

• GET, POST, PUT, PATCH, and DELETE with query parameters, non-secret headers, JSON or form bodies, and spreadsheet-cell variables.
• Encrypted bearer, API-key, Basic-auth, and custom-header connections resolved only between product services.
• Safe cURL import plus page-number, offset, next-URL, and cursor pagination.
• Saved imports with manual refresh and plan-controlled hourly, daily, or weekly schedules.

Local file imports and daily Free allowance

The testable Apps Script add-on can now open local .json files without uploading them to JSON for Sheets servers.

• Paste JSON, selected-cell JSON, local .json files, and public URL sources.
• Five successful external fetches per UTC day on Free; paid allowances reset monthly.
• Fresh URL previews, visual field selection, and overwrite, append, or one-key upsert output.
