为什么要把 XLS 转为 XLSX？
XLS and XLSX serve different roles in file workflows. Converting between them can make a file fit a particular editor, browser, upload form, archive, or delivery step, but the result should always be checked because layout, metadata, transparency, animation, or compression can change.
使用建议
Keep the original file until the output opens correctly in the application or service where it will be used. For images and media, compare dimensions, playback, transparency, and visible quality. For documents and data, check text encoding, page layout, delimiters, and special characters.
隐私与安全
Supported local conversions use browser processing and download APIs, so the selected file does not need to be sent to a conversion server. Browser memory and device capability still affect large jobs. Read the processing notice on the page before using sensitive material.
