Regex for Finance: Parsing Text Commands in n8n

I’ve been working on a project to automate expense tracking using n8n, a workflow automation tool. One of the key features is parsing text commands from Telegram messages.

The text command might look like this: ‘Paid 2000 for server hosting’. My goal is to extract the amount, category, and narrative from this text and push it to Firestore/Sheets.

I’ll break down the JavaScript Regex logic I use to achieve this. If you’re interested in learning more about regex and how to apply it to finance, stay tuned for the next part of this series.
