$5 BASIC MERGE SALE MESSAGE ME

Have multiple CSV or Excel files that you need combined into one clean, organized dataset?

I will combine your files into a single CSV or Excel file and check for common issues that could cause missing, duplicated, or incorrectly combined data.

This is more than a basic file merge. Your files are checked before and after processing, and files that don't safely match are flagged for review instead of being forced together.

My service includes:

  • Merge multiple CSV and Excel (.xlsx) files
  • Process CSV and Excel files together
  • Handle matching columns even when they're in different orders
  • Check file compatibility before merging
  • Verify that your data stays complete after processing
  • Separate questionable or incompatible files for review
  • Perform a final quality check before delivery
  • Deliver your finished dataset as CSV or Excel (.xlsx)

PDF Merge Summary Included: You'll receive a report showing the files processed, data handled, anything that required review, and your final output details.

Your finished dataset and report are delivered together in an organized ZIP package.

Need your data cleaned too? Optional data cleaning is available.
