A pick-and-place file (also called a centroid or XY file) is the list of exact positions, rotations and sides a pick-and-place machine uses to place every part on a board — but the CSV itself is just numbers next to reference designators, with no picture attached. This tool draws that picture: drop the file in and it plots every component at its recorded (X, Y), rotated the way the file says, colour-coded by which side of the board it belongs to.
Column names for this file type are not standardized — KiCad, Altium, Fusion 360, EasyEDA and JLCPCB's own exporters all use different header text for the same fields ("Mid X" vs "PosX" vs "Ref X", "Layer" vs "Side" vs "TB"). The tool detects the mapping automatically and shows exactly which column it used for which field, so a mistaken guess is visible rather than silent.
A search box filters and highlights by designator — type one reference or a comma-separated list like "R1, R2, U3" to pick out a handful of parts on a dense board. Toggle between top, bottom or both sides, hover any plotted rectangle (or a table row) to see its value and footprint, and click to pin the readout.
One honest limitation: most centroid files never declare whether their numbers are millimetres or inches. This tool only reports a unit when the file states it inline (some KiCad exports do); otherwise it says so plainly and lets a unit toggle just relabel the numbers rather than silently guessing which one is correct.
