The venue said it expects to break this record again today (1 August) with 30% more people travelling on the DLR than ever before to access the venue.
The numbers were thanks to Excel holding sports like table tennis and fencing, as part of the most complex programme of Olympic events of any venue in the London 2012 Games.
The centre is hosting seven Olympic and six Paralympic events and is the only venue to be staging events on every day of the Games.
Kevin Murphy, chief executive of Excel said: "So far everything has worked perfectly, with the transport infrastructure delivering everyone to the venue smoothly, whether they travel by train, plane or cable car, followed by a well-managed and rapid entrance into the venue, once they arrive onsite.
"Our events are running at near-capacity on every sport and feedback is overwhelmingly positive."
