About this service

Data cleaning scripts, report generators and Windows desktop tools in Python for jobs that outgrow a spreadsheet, delivered as a script or a program your team can run.

Sound familiar?

  • Files are too large for Excel to open comfortably
  • The same cleanup runs on dozens of files every month
  • Your team needs a small tool, not another spreadsheet
  • Data has to move between Excel, CSV, PDF and web systems

What I build

  • Scripts that clean, merge and reshape large files with pandas
  • Report generators that write formatted Excel and PDF files
  • Windows desktop and tray apps with a simple interface
  • Web automation with Selenium and requests
  • Packaged as a Windows program when your team has no Python installed

Try it: one click on a messy file

A small example of what a tool like this does with real-world data. Press the button.

FAQ

Do my users need Python installed?

No. I can package the tool as a Windows program so it runs with a double click.

Can it work with my existing Excel files?

Yes. Python reads and writes Excel, CSV and PDF, so it fits into the process you already have.

Will I get the source code?

Yes, the full source code is yours.

How long does it take?

Small fixes are often done the same or next day. Most builds take 2 to 3 days, and bigger systems about a week with a first version in 2 days. If you have a deadline, tell me and I will work to it.

How much does it cost?

The packages above have fixed prices. Pick the one that fits and pay securely. If your job does not fit a package, message me and I will send a custom offer with a fixed price before any work starts.

Is my payment safe?

Yes. Card and PayPal payments go through PayPal or Razorpay, so your card details never touch this site. If the delivery is not what the package describes, tell me within 3 days of delivery and show what does not match, and you get your money back.

What happens after I order?

You answer a few questions and upload your file. I start right away, we talk inside the order page, and you get the delivery there with the files. You can ask for changes up to the number of revisions in your package.
