Nick Burch commented on TIKA-2025:
----------------------------------

We could always test the formatted value for {{E+}} (or {{E-}}?) on the end, 
and re-do with our own no-exponent formatter for that case. Would need a note 
about why we're doing it though!

> Extraction of long sequences of digits from Excel spreadsheets using Tika 
> 1.13 doesn’t yield the expected results

>             Project: Tika
>          Issue Type: Bug
>          Components: parser
>    Affects Versions: 1.13

> 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.
