Enrich German vocabulary in Google Sheets with OpenThesaurus and OpenAI

Quick Overview This workflow watches a Google Sheets vocabulary list for new German words, looks up synonyms via OpenThesaurus, and uses an OpenAI chat model to generate a JSON-formatted example sentence with metadata, then writes the results (or a “not found” note) back to the same sheet.

How it works Triggers every minute when a new row is added to the selected Google Sheets worksheet. Sends the new row’s vocabulary value to OpenThesaurus to retrieve the headword and available synonyms. Checks whether OpenThesaurus returned any terms and, if none are found, updates the row in Google Sheets with a “類義語が見つかりませんでした。” message. If terms are found, prompts an OpenAI chat model (via an AI Agent) to output strict JSON containing a natural German example sentence using a synonym, the part of speech, a Japanese translation, and a CEFR level estimate. Extracts the JSON fields and updates the matching Google Sheets row with the generated sentence, part of speech, translation, and level.

Setup Connect your Google Sheets OAuth credentials and select the target spreadsheet and worksheet for both the trigger and update steps. Ensure your sheet has columns named vocabulary, Similar Examples sentence, part_of_speech, translation_ja, and level, and that vocabulary can be used to match/update rows. Add OpenAI credentials (or an OpenAI-compatible connection) for the OpenAI Chat Model used by the AI Agent, and confirm the model name is available in your account. Enter new German words in the vocabulary column to test, and verify the OpenThesaurus lookup returns terms for your input words.
