How to save a 2D array to a Script Property in Properties Service in Google App Script?

问题

I have a 2D array that I need to save as a property in Google App Script. How would I do this?

var array = [['value 1', 1.0, 'A'],['value 2', 2.0, 'B'],['value 3', 3.0, 'C']]

PropertiesService.getScriptProperties().setProperty('myArray', array)

When I run the code as listed above I get [Ljava.lang.Object;@40ac055f as the value.

When I us array.toString() the property value negates the square brackets.

Thanks in advance!

• Note that Properties Store is meant to save specific properties and key values. It's not meant to be a replacement for the entire spreadsheet.

• Current quotas1 limit the property value size per key to 9kB and total storage per store to 500kB.

• If your requirement doesn't cross the limit described above, the easy way is to use JSON.stringify2, Which will convert it to a parsable string.

  var array = [['value 1', 1.0, 'A'],['value 2', 2.0, 'B'],['value 3', 3.0, 'C']];
  var jarray = JSON.stringify(array);
  PropertiesService.getScriptProperties().setProperty('myArray', jarray);
  

• You can then use JSON.parse3 to retrieve the array

  var array = JSON.parse(jarray);
