Phantom Numbers saved as a strings changing when outputting file to .xlsx or .csv

[BrendanCallery]

This is a weird one! 

I have serial numbers that looks something like this in a table in my workflow:

224884905

when I write my final output to a .csv or .xlsx I will get:

224884205

it doesn't seem to be happening in the first digits but when there is a 2 or 9 in the middle of the string the number will flip to 9 or 2. Any theories on how this may be happening would be extremely appreciated.

Hi @BrendanCallery 

Can you share a workflow that reproduces this behaviour? Isolating just the necessary parts to observe the issue.
