Is it to late or too late?
It is too late, not to late (e.g., “I checked online to see if there were any tickets left for the concert, but we’re too late; they’re all sold out”).
Use the adverb of time “late” without “too” if you just mean “after the arranged time” (e.g., “Sorry I’m late,” or “I missed the bus and was half an hour late”).
