I was sick of the daily copy‑paste marathon – opening the spreadsheet, drafting a caption, then hopping between four APIs. With n8n I wired Google Sheets as the source, let Groq generate the text, and used the LinkedIn, Facebook, Instagram and Threads nodes to push the image everywhere. The workflow also flips a “published” flag back in the sheet. Roughly 20 minutes saved per project, and I finally trust the process to run on its own.
