Paste a column of SMILES, drop a CSV or an SDF, and every structure in the list is converted at once. The table comes back out as a CSV or an SDF, with the structures drawn beside their notation.
Convert between chemical structures and SMILES in both directions, search a list of structures by substructure or SMARTS, and learn the notation step by step. Everything runs in your browser — no structure you open ever leaves your machine — so the tool needs JavaScript.
