I have a single-sheet Excel file that lists many clients, one row per person. For each row the tool must read the name, date of birth, plus couple other extra identification fields, open the target web platform in a fresh GoLogin profile that uses a country-specific proxy, complete the single-page form, submit, then delete the profile before moving to the next client. Key points you must handle: • Windows-friendly .exe that runs without external installs. • Direct reading of my existing .xls format (no manual conversion). • Seamless control of GoLogin: create profile → assign proxy → launch browser → close and remove profile programmatically. • Robust field mapping so every required piece of data is placed in the correct form element. • Graceful error logging—if one record fails, the run continues and a log shows which client needs manual review. If you are already comfortable with this through GoLogin and parsing Excel in a compiled language (Python with PyInstaller, C#, or similar), send me a short note confirming you can meet the above workflow and timeline; no lengthy boilerplate is necessary.
