MoammarIqbal/Pedas2025 — reverse-engineered prompt

Build me a simple analysis project using the data files in this folder. I want to understand Indonesian car sales from 2021 to 2025 and how they might relate to inflation, foreign exchange rates against Rupiah, and GDP.

Please clean and combine the CSV and Excel files, handle messy dates or missing values, and make the results easy to explore. I’d like clear charts that show car sales over time, inflation trends, exchange rate movement, and GDP changes. Also include a section that explains in plain language whether these numbers seem connected to car sales, without making it too technical.

Make it easy for someone nontechnical to run and view. A small dashboard or simple report is fine, whichever makes more sense from the data. Add short notes explaining what each chart means, and include a final summary with the main insights from the data.
