Values populating in listbox through various excel sheets are different and not in sync?

[#1]

I had few data sources and it  has few data in columns that is more than 15 characters (approx 18). So while loading them I am getting ambiguous values and last 4 digits are different.

For example:

Data in excel sheet is as per below:

-9182910008952620000

After loading in qlikview I am getting below data:

-9182910008952621100

I can't modify the data as it is a legacy data any way around to solve this?

Only by converting the values to text. Numbers in Qlikview are IEEE 754 floats. See this discussion: Number too large to parse as number?
