[TIKA-3544] Extraction of long sequences of digits from Excel spreadsheets using Tika 1.20 doesn’t yield the expected results

• Type: Bug

Description

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 “6011799905775830” is extracted from the attached spreadsheet as 6.480195344642784E15, which clearly is not the desired output.

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.
