Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
POST /v4/spreadsheets/{id}/values/{sheetName}!A1:append with valueInputOption and insertDataOption=INSERT_ROWS
The range parameter is a table hint — the API finds the last row of the contiguous table
Read back updatedRange from the response to know where data landed
Use a lock/queue if multiple writers append concurrently
Known gotchas
append finds the end of the CONTIGUOUS data block — a blank row makes later appends overwrite from the gap
Concurrent appends can interleave; the API has no transactions
Cell limit 10 million per spreadsheet — plan archival
