CSV Diff Tool

A CSV Diff Tool is a data comparison utility used to find discrepancies between spreadsheets. This tool is essential for data analysts, accountants, and engineers auditing financial reports, verifying database migrations, and merging customer lists.

The "Structured" Diff

Unlike a standard text comparison, this engine parses the CSV structure:

1. Key Matching: It can match rows by a unique "ID" column, even if the row order has changed.
2. Column Alignment: It ensures that "Price" compares to "Price," even if the columns are in a different order in the second file.
3. Value Check: It detects subtle changes like trimming whitespace or floating point differences (1.00 vs 1).
