I will build excel automation tools with csharp and dotnet
Kamal Mansouri
About this gig
Stop doing the same Excel work every week.
I'm a senior .NET software architect with 10+ years building enterprise systems. I turn slow, error-prone manual spreadsheet work into a tool you double-click.
What I can automate for you:
Merging and cleaning data from multiple Excel/CSV files
Generating formatted reports with formulas, styling and charts
Converting Excel to PDF, or database data into Excel
Importing spreadsheets into SQL Server or your existing system
Scheduled or folder-watched processing that runs unattended
Why C# instead of VBA macros: macros break, are slow on large files and often get blocked by IT policy. I deliver a standalone Windows application that handles hundreds of thousands of rows reliably, with proper error handling.
What you get: a ready-to-run .exe (no Office license or installation required on your side), clear instructions, and a tool that keeps working after our order closes.
Not sure which package fits? Message me with a sample file and what you need I'll tell you honestly in a few minutes, no obligation.

Senior .NET architect with 10+ years building software for companies that can't afford it to break.
I turn repetitive manual work into tools that just run: Excel automation, Windows desktop apps, REST APIs and third-party integrations, and rescuing C# projects someone else left half-finished.
What you get: an honest answer before you order, a scope we both understand, and code you can still maintain in two years.
Based in Spain (CET). I speak English, Spanish, French and Arabic.
Send me your file and what you need. I'll tell you straight if I'm the right fit.
FAQ
Do I need Microsoft Office installed?
No. The tool reads and writes Excel files natively.
Can it handle very large files?
Yes — I regularly work with files of hundreds of thousands of rows.
Will you use my real data?
Only if you want. Dummy data works fine for development, and I delete everything after delivery.
Do I get the source code?
Included in Premium, available as an extra otherwise.
Can you connect it to my database or existing software?
Yes — SQL Server, MySQL, PostgreSQL, REST APIs. Message me first so I can quote it properly.
