Store Data in a Cloud Expression

Create a cloud expression

Put the expression {1,2,3,4,5} in the cloud:

Wolfram Language code: ce = CreateCloudExpression[Range[5]]
  • Cloud expressions reside in the Wolfram Cloud and persist from session to session.

Retrieve the cloud expression

Get the value of the cloud expression:

Wolfram Language code: Get[ce]

Add data to the cloud expression

Append a value to the cloud expression:

Wolfram Language code: AppendTo[ce, 66]

Get the updated cloud expression:

Wolfram Language code: Get[ce]

Change data in the cloud expression

Change the value of the third element in the cloud expression:

Wolfram Language code: ce[[3]] = 33

Get the updated cloud expression:

Wolfram Language code: Get[ce]

Delete data in the cloud expression

Delete the second element in the cloud expression:

Wolfram Language code: ce[[2]]=.

Get the updated cloud expression:

Wolfram Language code: Get[ce]

Compute with the cloud expression

Plot the values in the cloud expression:

Wolfram Language code: ListPlot[Get[ce]]

Notes

Cloud expression operations include Get, Put, Unset, Length and Increment. See the CloudExpression documentation for a complete list.
Give others access to a cloud expression by specifying Permissions->"Public":
Change the permissions of an existing cloud expression using SetPermissions. This cloud expression is accessible only by the owner:
Wolfram Language code: ce = CreateCloudExpression[Range[5]]
Wolfram Language code: Options[ce]
Change the cloud expression’s permissions to give others access to it:
Wolfram Language code: SetPermissions[ce, "Public"]
Now anyone can read the cloud expression:
Wolfram Language code: Options[ce]
