Subject [jira] [Comment Edited] (TIKA-2025) Extraction of long sequences of digits from Excel spreadsheets using Tika 1.13 doesn’t yield the expected results

16 digit?  Is the last digit 0?  If so, that might be truncation/flooring.  If not, are you
sure it is stored as a number, perhaps formatted as text?

>             Project: Tika
>          Issue Type: Bug
>          Components: parser
>    Affects Versions: 1.13
>            Reporter: Aeham Abushwashi
>            Assignee: Tim Allison
>             Fix For: 2.0, 1.14

> If an Excel spreadsheet contains a long sequence of digits, such as a credit card number,
Tika 1.13 will emit the said sequence in scientific notation.
> For example, the credit card number “340229177292566” is extracted from the attached
spreadsheet as 3.40229E+14, which clearly is not the desired output. 
> This works as expected in 1.12 and earlier. I suspect POI’s recent use of org.apache.poi.ss.usermodel.ExcelGeneralNumberFormat
is to blame.
> I think the impact of this issue is significant. There’s plenty of information that
can no longer be reliably extracted from spreadsheets. Think credit card numbers, telephone
numbers and product identifiers to name a few.
