CSV Compare

Package csv-compare helper provide an API to process CSV files with the same structure (columns).

The process results in a list of unique rows, in reverse order.

You can compare 1 (deduplication) or more files.

Current capabilities

• deduplication (self-comparing) : top row has the precedence
• deduplication for n files
• not revert: on most case we want to have a diff file in FIFO style, this is the default behaviour, but sometimes you do not want.

Installation

go get github.com/Climberdav/csv-compare
