Free CSV File Joiner

ByKandZ

Merging two CSV files by hand is a nightmare.

You copy, paste, and inevitably misalign a row. You forget a matching key. The data shifts.

I built a free tool that solves this.

What it does:

  • Joins two CSV datasets
  • Supports inner, left, and full outer joins
  • Uses common primary keys

Use cases:

  • Combining user data with order data
  • Merging exports from different systems
  • Building unified reports
  • Fixing fragmented datasets

Privacy:
100% client-side. Nothing uploaded.
