APEX Document Generator: Null values replaced by non-breaking spaces (\u00A0) in JSON

KevinLennozMay 6 2026

Hello everyone,

I am using the Document Generator for an APEX application. I am populating a report query using table values, but I've encountered an issue with null columns.

Instead of being null or empty, these columns are appearing in the generated JSON as non-breaking spaces (\u00A0).

Due to that, the XLSX template is populated with "space" (the cells are not empty).

Thank you for your help

Please see the JSON example below:

{

"change\_personal\_info": \[

    {

        "spreadsheet\_key": 1,

        "c": "213152",

        "e": "FRA",

        "f": "1982-07-28",

        "g": "FRA",

        "h": "FRA-50",

        "i": "F",

        "l": "\\u00A0",

        "o": "\\u00A0",

        "aj": "FR\_C",

        "am": “FRA”

    },

    {

        "spreadsheet\_key": 2,

        "c": "213153",

        "e": "FRA",

        "f": "1965-08-31",

        "g": "FRA",

        "h": "FRA-50",

        "i": "M",

        "l": "\\u00A0",

        "o": "\\u00A0",

        "aj": "FR\_C",

        "am": “FRA”

    }

\]

}
