Convert email attachments into structured spreadsheet rows
Extract attachments from incoming emails and parse them automatically into rows of a Google Sheet using a delegated service account.

| Typical scopes | gmail.readonly, sheets |
The problem
Manual extraction of data from email attachments is error-prone and slow, especially at volume. Automating this saves time but requires careful handling of message contents and spreadsheet updates.
How it works
- Use the Gmail API via a delegated service account to list and fetch relevant emails and attachments.
- Parse each attachment (e.g., CSV, XLSX, PDF) into structured data.
- Transform the extracted data into the format required by the destination Sheet.
- Batch append rows to the Sheet using the Sheets API, handling duplicates and errors.
- Track processed message-IDs to avoid reprocessing.
What changes
Attachments are ingested and parsed into live spreadsheet data without manual intervention, enabling real-time reporting or workflows.

Questions people ask
How do you avoid duplicate rows if an email is processed twice?
Store and check message-IDs (or attachment hashes) before inserting, and use Sheets API batch operations to reduce race conditions.
What file types are safest for automated parsing?
CSV and plain text are most reliable; XLSX and PDF require additional libraries and error handling for malformed or password-protected files.

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
