Google Sheets#

Connect Google Sheets with Google OAuth and one or more selected spreadsheets. The source writes one discovered table per visible sheet tab under titan.google_sheets.

Connect Google Sheets#

  1. Open Apps, choose Connect app, and select Google Sheets.

  2. Enter Google OAuth and one or more selected spreadsheets.

  3. Review the tables, then save the source.

  4. Watch Sync history until the first run completes.

Credentials are stored as secrets. They never become lake columns or appear in query results.

Sync behavior#

Supernova infers types from 100 rows, forward-fills merged cells, and adds _sn_row_number so row identity remains explicit.

A new source syncs when you connect it and then follows its schedule. The default recurring interval is 4 hours. An interrupted run keeps its completed progress and retries safely.

Every lake table also has the system columns _synced_at and _deleted; the column reference below lists source columns only.

Table reference#

Supernova discovers this reference from the connected account. Spreadsheet titles, sheet tabs, headers, and inferred types define the reference after setup.

Open Apps → Google Sheets → Tables after the first discovery run to see every exact table name, column name, type, and sync selection. Dynamic fields cannot be listed truthfully before an account is connected.

Deletes and history#

Rows are merged by their source key. When the source can prove that a row was deleted, Supernova keeps the row and sets _deleted so queries can choose whether to include history. Filter current-state queries with where not _deleted.
