Drag the formula over the two columns to the bottom of the pick and place file to fill all of the cells.

In a new column add a new formula as follows to add the “mm” units to the value. If the first Metric X value is at H13, the formula is: =CONCAT(TEXT(H13,”0.000”), ”mm”)

Drag the formula over the two columns to the bottom of the pick and place file to fill all of the cells.

Add the “Designator”, “Layer”, “Rotation”, “Mid X” and “Mid Y” titles to the following columns

Copy the new “Mid X” and “Mid Y” columns and paste them into a new column using the “Paste as Text” functionality
