Google Apps Script Libraries

Libraries are reusable Apps Script projects you import by ID — Google's own OAuth2 library is the canonical example, but the ecosystem has grown well beyond it. The libraries below cover authentication, rate-limited HTTP clients, batch Sheets operations, structured logging, parsing, and Workspace API ergonomics. Each entry links to its source, install instructions, and version notes.
