Hello !

I form an array like:

Array
(
    [0] => Array
        (
            [NAME] => Иванов
            [LAST_NAME] => Иван
            [UF_SELECT_MON] => Array
                (
                    [0] => 1362
                )

            [UF_SELECT_TUE] => Array
                (
                    [0] => 1362
                    [1] => 1363
                )

            [UF_SELECT_WED] => Array
                (
                    [0] => 1362
                    [1] => 1363
                )

            [UF_SELECT_THU] => Array
                (
                    [0] => 1362
                    [1] => 1363
                )

            [UF_SELECT_FRI] => Array
                (
                    [0] => 1362
                )

            [UF_SELECT_SAT] => Array
                (
                    [0] => 1362
                )

            [UF_SELECT_SUN] => Array
                (
                    [0] => 1362
                    [1] => 1363
                )

            [UF_ADDRESS] => 1374
        )

    [1] => Array
...

UF_SELECT_MON, UF_SELECT_THU... store element IDs in the infoblock. You need to get the names of the elements and how to write it to an EXCEL file, by type:
User | Day of the week | Dish
adm | Monday | <list of items here>

Any help would be welcome.

Thank you !

An array is formed in CIBlockElement::GetList ???
If yes, then there you can make a selection by related elements. In the sample array:

PROPERTY_WHATEVER.NAME

You can write to csv using fputcsv.
