Calamo Pro is a desktop app for two jobs: comparing an old and a new export by a key column, and browsing a file too big for Excel. Files are read from your disk and never leave the computer.

Open two files, Calamo picks the key and compares; sort by price, jump to the next change with F8, switch to added rows.

Compare two files in a minute

  1. Drop the older file on A and the newer file on B, or use File → Open older file (A)… (Ctrl+O) and Open newer file (B)… (Ctrl+Shift+O).
  2. Calamo suggests a key column, a column with a different value in every row such as an ID, and compares right away.
  3. Read the counts at the top: changed, added, removed and unchanged rows. The status bar shows that every row of both files is counted once.
  4. Save the result with Save report… (Ctrl+S), or pass on a marked copy of the new file.
Start screen with drop areas for file A and file B
The start screen: two drop areas, the files you compared recently, and a link to browse one file.

Display

Calamo follows the light or dark appearance of your system. View → Theme sets it to light or dark for good, Alternate row shading shades every other row, and Larger rows makes the tables easier to read on a large screen. Calamo remembers these choices.

The comparison in the dark theme
The dark theme: the change colours stay the same.
