I understand that you need a program that compares .txt files to create a new column with information from Col 0, Col 1 and Col 2 that can then be used to compare the keys from both files in order to identify which rows exist in DB1 but not DB2. This requires the program to run fast and take no longer than 2 hours to complete the task. I believe I have the skills necessary to tackle this project - specifically advanced Excel formulas, visual basic, Excel macros, statistical data analysis, correlation and regression analysis, multiple regression analysis, excel reports, pivot & chart, advanced excel formulas and sales analysis. In addition to this I also have access to Google Sheets which would be invaluable when it comes to analyzing data offline quickly.

Hello, I have checked the given link. We can even settle down at ****** 25$ ********** I will efficiently fulfill your data comparison needs by proposing the creation of a Python script utilizing Pandas for swift and effective data manipulation. The script is designed to read two sizable .txt files, generate a new column by combining information from specified columns, and conduct a comparison to identify rows existing in "DB1" but not in "DB2." By harnessing the potent capabilities of Pandas, the process will be optimized for speed. To accommodate the 2-hour time constraint, the program will be tailored to handle large datasets effectively. The output will be produced in an Excel file, offering a clear summary of rows present in "DB1" but absent in "DB2." I will proceed with the development, ensuring a robust solution that aligns with your requirements and is delivered within the specified timeframe.

Hello Sebastian, I'm interested in assisting with your task of comparing two large .txt files containing real estate data. To ensure efficiency, I would write a Python script to perform this operation. However, before proceeding, could you clarify whether you have any specific requirements for the output Excel file format, such as column headers or naming conventions? Additionally, to optimize the script's performance, are there any constraints on the hardware or environment in which it will run? Thank you for considering my interest in your project. I look forward to a more detailed discussion to tailor the solution to your specific needs. Thanks.
