Telegram Expense Logging via GPT-4.1 to Google Sheets

This powerful n8n workflow automates personal expense tracking through a seamless integration of Telegram, OpenAI GPT-4.1, and Google Sheets. The workflow starts with listening for user messages via Telegram, where users can easily send expense details in plain text. When a message is received, it is checked to ensure it’s a text message. The message is then processed by GPT-4.1 Mini, which wisely extracts structured expense data such as date, amount, category, and description, along with a friendly confirmation message. If the message contains relevant expense information, the workflow automatically responds with acknowledgment and logs the expense into a specified Google Sheet. Eligible messages result in a logged expense entry with details like date, amount, category, and description, making this ideal for individuals or small teams seeking quick, hassle-free expense tracking through straightforward chat commands. If the message is not a valid expense, the bot politely informs the user it cannot process non-relevant messages, ensuring a smooth and supportive experience.

This workflow is highly practical for freelance workers, busy professionals, or small businesses who want effortless expense management, by simply chatting with a Telegram bot and letting n8n handle the rest, storing all data in an organized Google Sheet for easy review and analysis.
