Simple excel automation

I need a simple Windows-based automation that runs once per day, 7 days a week. This is first of many simple automations. The process is: Log into 2 websites using credentials I will provide securely. Download 1 Excel report from each website. Combine/match the two reports primarily using a common field. Apply approximately 5-10 simple formulas/conditions. Refresh a simple Excel dashboard showing the required results. Automatically save/overwrite the finished dashboard in a designated Dropbox folder every day. I am open to Power Automate Desktop + Power Query, Python, or another simple/reliable solution. I care more about reliability and ease of maintenance than sophisticated coding. Requirements: Fully automated after initial setup Runs daily without manual intervention Handles the two website downloads Refreshes Excel data/formulas Outputs a clean Excel dashboard to Dropbox Basic error handling if a website/report is unavailable Provide source files/code and brief instructions so I can maintain it Fixed budget: $100 This is a small project — only two files and a few formulas. Please only apply if you have done browser + Excel automation before. In your response, tell me what technology you would use and why.
