FAQ
Q: Will the tool verify whether an ID number is genuinely valid?
A: The current feature focuses on "batch extraction," mainly identifying the 18-digit ID number format, and does not judge the issuing region or the authenticity of the check digit.
Q: Why is the result count lower than what I see in the original text?
A: If "automatic deduplication after extraction" is enabled, duplicate ID numbers are merged, so the result count decreases.
Q: Which formats can I export?
A: TXT and Excel export are supported, making text archiving and spreadsheet analysis convenient.
