CSVLane

CSVLane is a free CSV workbench that runs entirely in your browser tab: files are never uploaded and there is no account. Compare two CSV exports or Excel .xlsx workbooks by an ID column and see added, removed and changed rows cell by cell, even when one file has been re-sorted. Clean a CSV by trimming spaces and removing empty and duplicate rows, change the delimiter between comma, semicolon, tab and pipe, read encodings such as Windows-1252, and download UTF-8 CSV with or without a BOM, or JSON. Every change is listed before you download.
