Subscript Numbers in Chemical Formulas

This tool applies subscript formatting to the numbers in chemical formulas in your selected text cells.
It automatically detects where the numbers should be subscripted based on standard chemical notation.

This includes element counts (e.g., H₂O), numbers inside parentheses (e.g., NO₃)₃, and hydrate notations using dots (e.g., · 4H₂O).
All other formatting in the cell remains unchanged. Cells that contain formulas, numbers, or dates are skipped.

Examples where numbers are formatted as subscript:

• "H2O" becomes "H₂O" (Water)
• "C8H10N4O2" becomes "C₈H₁₀N₄O₂" (Caffeine)
• "C6H12O6" becomes "C₆H₁₂O₆" (Glucose)
• "Al(OH)3" becomes "Al(OH)₃" (Aluminum hydroxide)
• "Ca(NO3)2 · 4H2O" becomes "Ca(NO₃)₂ · 4H₂O" (Calcium nitrate tetrahydrate)
• "NaHCO3" becomes "NaHCO₃" (Baking soda)
