I am trying to save react-seat-picker data into firestore and read it back.

The one piece of code describing data that should be written/saved to firestore is this:

 const rows = [
      [{id: 1, number: 1, isSelected: true, tooltip: 'Reserved by you'}, {id: 2, number: 2, tooltip: 'Cost: 15$'}, null, {id: 3, number: '3', isReserved: true, orientation: 'east', tooltip: 'Reserved by Rogger'}, {id: 4, number: '4', orientation: 'west'}, null, {id: 5, number: 5}, {id: 6, number: 6}],
      [{id: 7, number: 1, isReserved: true, tooltip: 'Reserved by Matthias Nadler'}, {id: 8, number: 2, isReserved: true}, null, {id: 9, number: '3', isReserved: true, orientation: 'east'}, {id: 10, number: '4', orientation: 'west'}, null, {id: 11, number: 5}, {id: 12, number: 6}],
      [{id: 13, number: 1}, {id: 14, number: 2}, null, {id: 15, number: 3, isReserved: true, orientation: 'east'}, {id: 16, number: '4', orientation: 'west'}, null, {id: 17, number: 5}, {id: 18, number: 6}],
      [{id: 19, number: 1, tooltip: 'Cost: 25$'}, {id: 20, number: 2}, null, {id: 21, number: 3, orientation: 'east'}, {id: 22, number: '4', orientation: 'west'}, null, {id: 23, number: 5}, {id: 24, number: 6}],
      [{id: 25, number: 1, isReserved: true}, {id: 26, number: 2, orientation: 'east'}, null, {id: 27, number: '3', isReserved: true}, {id: 28, number: '4', orientation: 'west'}, null,{id: 29, number: 5, tooltip: 'Cost: 11$'}, {id: 30, number: 6, isReserved: true}]
    ]

You can stringify your nested array (JSON.stringify(rows)) before storing in firestore and parse it after getting it back.

So far firebase firestore doesn't support nested arrays,you need to change the data structure.Have a look at this solution
