v2.14.1

Fixed

• A failed Sheets append said only Failed to write data. Home Assistant's
  google_sheets integration wraps every underlying API error in that one
  string, and the cause — which carries the status code and Google's own
  message — was dropped on the floor. The warning now names the worksheet and
  the chained cause, so a too-narrow sheet, a revoked token and a quota
  rejection stop looking identical.
• export_all worked through every remaining day after a structural failure,
  turning one misconfiguration into one warning per day. It now stops after
  five consecutive failures and says why.
• export_all sent its appends as fast as it could manage. The Sheets API
  allows 60 writes per minute, so a forced export of a long range spent its
  tail being rejected for quota. Appends are now paced.

Documentation

• The column table listed 15 columns; the integration writes 19. Week,
  Month, Top-up type and Top-up hours were missing. A sheet built to
  match the old table is too narrow to accept a row.
• Documented that the worksheet needs at least 20 columns: the 19 written
  here plus the created column that google_sheets adds to every row. A grid
  that stops at 19 rejects the entire write with exceeds grid limits.
