Rons Data Compare is a desktop tool for reviewing differences between two CSV files. It is suited to people who maintain changing lists or tabular records and need to identify additions, removals, and edits without inspecting each file line by line. Customer lists, inventories, exports, and other structured data can be opened as a paired comparison, with both tables displayed side by side.
The comparison view highlights differences in individual cells, rows, and columns, making it easier to trace what changed and where. Comparison statistics provide a summary of the amount of difference between the files. The program can compare rows in their existing order or match them by a selected column, such as an ID or name. This is useful when entries have been rearranged: matching by a key column can align corresponding records even when their positions differ. It can also compare selected parts of rows, helping focus a review on the information that matters.
The two documents can be swapped, and multiple comparisons can remain open in separate tabs. A Locations panel helps find documents and assign them to either side of a comparison. Comparison mode can be turned off to edit the files as tables, then enabled again to inspect the effect of changes. Undo and redo are available during editing, so corrections can be reviewed or reversed without losing the comparison workflow. Tables copied from websites or Markdown documents can also be imported, for example when adding externally sourced information to an existing CSV.
These features support routine data checks such as comparing an older customer export with a current one, checking whether records were added or removed, and locating changed values after a spreadsheet or database export. Matching on an identifier is particularly helpful when the same records appear in a different order or when columns are arranged differently between files. The side-by-side layout keeps the source and updated data visible together, while highlighting and statistics help users move from an overall check to specific discrepancies.
Rons Data Compare is trialware for Windows. It supports Windows 10 and Windows 11, as well as Windows 8, in 32-bit and 64-bit editions. It is intended for CSV-based comparison and editing rather than as a general-purpose spreadsheet or database system.
