“First, we need two libraries: rdkit for chemistry and pandas for tables.” how to convert sdf file to csv
“For the non-programmers on our team,” Elena continued, “we use KNIME. Drag an ‘SDF Reader’ node, connect it to a ‘CSV Writer’ node, and configure which columns to keep. It’s visual—like drawing a flowchart.” Within an hour, Elena handed Leo the final compounds
