[GUI Plugin] ShelfBridge - Export your library to Goodreads/StoryGraph, Google Sheets

[kaylaehman]

ShelfBridge exports your Calibre library to reading-tracker and productivity services.

Supported services

• Goodreads / StoryGraph — a CSV in the Goodreads import schema (StoryGraph accepts the same file). No account setup needed.
• Google Sheets — writes your catalog into a Sheet you own. Re-exports are idempotent (the sheet is cleared and rewritten), so scheduled runs never pile up duplicates.
• OneDrive — uploads the CSV via Microsoft Graph (device-code sign-in).

Features

• CSV written UTF-8 with BOM so it opens cleanly in Excel.
• Credentials stored in your OS keychain (Windows Credential Manager / macOS Keychain / libsecret), with a clearly-logged plaintext fallback.
• Automatic retry/backoff that honours rate-limit Retry-After headers.
• Automation: export on library change or on a schedule (15 min through daily).
• Read-only with respect to your Calibre library.

Installation
Download the attached shelf_bridge.zip, then in Calibre: Preferences -> Plugins -> Load plugin from file. Restart when prompted. A ShelfBridge button appears on the toolbar.

Setup
Goodreads/StoryGraph need only an output folder. OneDrive and Google Sheets each need a free, one-time OAuth app — step-by-step instructions are in the README:

Sounds like a hot idea but where is config?

Is there ANY CHANCE of fixing it to send up multiple read dates?
