    How to finish your task

    Inspect author metadata, comments, hidden sheets and external-link traces. Add files and review settings. Create the result, check the preview, actual size and limitations, then download a new file.

    Practical example

    Before sharing, inspect metadata, comments, hidden rows/columns, embedded files and macro traces. Make changes in the original editor.

    Scope and limitations

    Inspection only: sources are not modified. 30 MB input, 2,000 ZIP entries and 100 MB expanded limit. Encrypted/protected files are unsupported; this is not exhaustive privacy certification.

    Files are not uploaded to a server. Outputs are new files, so originals remain unchanged. Review the result before saving.

    When is this useful?

    Inspect author metadata, comments and hidden-content traces before sharing Office files, then edit them in the source application.

    Input and result example

    Office file → hidden-information inspection report

    Examples illustrate the workflow; actual size, support and recognition depend on the source and settings.
