Tim Allison reassigned TIKA-2025:
---------------------------------
Assignee: Tim Allison
> Extraction of long sequences of digits from Excel spreadsheets using Tika
> 1.13 doesn’t yield the expected results
> -----------------------------------------------------------------------------------------------------------------
>
> Key: TIKA-2025
> URL: https://issues.apache.org/jira/browse/TIKA-2025
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.13
> Reporter: Aeham Abushwashi
> Assignee: Tim Allison
> Attachments: Credit Card Numbers.xlsx
>
>
> 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.
