Simple Data Cleaning & Standardization — 1,570-row Dataset (€30)

Hi, I have a small dataset with about 1,570 rows and 10 columns. It’s a bit messy — some cells have missing values, mixed date formats, extra spaces, numbers with symbols (€, $, commas, etc.), and a few duplicate or empty rows.

I just need someone to clean and standardize it so it’s ready for analysis.
Here’s what I expect:

Fix missing or placeholder values (N/A, unknown, blanks).

Make all dates the same format (YYYY-MM-DD).

Convert numeric fields to proper numbers (remove symbols, text, commas).

Remove duplicates and empty rows.

Trim extra spaces from text.

Please deliver a clean CSV file (UTF-8, no header row needed) and a short note describing what you did.
