Objects

Cell Object

columnId	number The Id of the column that the cell is located in.
columnType	string Only returned if the include query string parameter contains columnType.
conditionalFormat	string The format descriptor describing this cell's conditional format. Only returned if the include query string parameter contains format and this cell has a conditional format applied.
displayValue	string Visual representation of cell contents, as presented to the user in the UI.
format	string The format descriptor. Only returned if the include query string parameter contains format and this cell has a non-default format applied.
formula	string The formula for a cell, if set, for instance =COUNTM([Assigned To]3). Note that calculation errors or problems with a formula do not cause the API call to return an error code. Instead, the response contains the same value as in the UI, such as cell.value = "#CIRCULAR REFERENCE".

	object
	Array of objects
	AbstractDatetimeObjectValue (object) or CheckboxObjectValue (object) or ContactObjectValue (object) or DateObjectValue (object) or DatetimeObjectValue (object) or DurationObjectValue (object) or MultiContactObjectValue (object) or MultiPicklistObjectValue (object) or PredecessorListObjectValue (object) The base object for values found in the Cell.objectValue attribute. Its objectType attribute indicates the type of the object. This object itself is not used directly.
overrideValidation	boolean (Admin only) Indicates whether the cell value can contain a value outside of the validation limits (value = true). When using this parameter, you must also set strict to false to bypass value type checking. This property is honored for POST or PUT actions that update rows.
strict	boolean Set to false to enable lenient parsing. Defaults to true. You can specify this attribute in a request, but it is never present in a response.
	string or number or boolean A string, number, or a Boolean value -- depending on the cell type and the data in the cell. Cell values larger than 4000 characters are silently truncated. An empty cell returns no value.

CellLink Object

columnId	number Column Id of the linked cell.
rowId	number Row Id of the linked cell.
sheetId	number Sheet Id of the sheet that the linked cell belongs to.
sheetName	string Sheet name of the linked cell.
status	string `BLOCKED` One of several other values indicating unusual error conditions. `BROKEN` The row or sheet linked to was deleted. `CIRCULAR` One of several other values indicating unusual error conditions. `DISABLED` One of several other values indicating unusual error conditions. `INACCESSIBLE` The sheet linked to cannot be viewed by this user. `INVALID` One of several other values indicating unusual error conditions. `NOT_SHARED` One of several other values indicating unusual error conditions. `OK` The link is in a good state.
