Set cell to long number value without rounding

Hi,

I'm sure I'm just missing something obvious but I have a raw data set, which I'm putting into a dictionary.

One of the values is an ID, which can (but not always) be a 20 digit number.

I've got it into the dictionary by defining the item as variant, and it's being stored as "Variant/String" and it stored in the dictionary without rounding - which is perfect.

However I'm then trying to get those values into the spreadsheet, by looping through the dictionary and setting certain cells equal to certain values, but every time I try to put this ID into Excel, it rounds after 10 digits.

Can someone please help?

I'm trying:

Cells([row],[column]) = DictionaryEntry.ID

And I'm totally lost.

Thanks in advance!

Edit: Probably not the smartest solution but I just went in a formatted the relevant columns a text field prior to putting the values in. Thanks for everyone's help
