NUMBERS at a glance
NUMBERS
Convert to NUMBERS when the recipient is expected to work further in Apple Numbers, especially for schedules, lightweight financial sheets, classroom materials, or visually arranged tables in Mac- and iPad-based workflows.
It is useful when the Apple editing experience matters more than cross-platform ubiquity.
For broad office interoperability, XLSX is usually the safer spreadsheet target.
SVGZ at a glance
SVGZ
Convert to SVGZ when you need SVG semantics but want the file itself stored or transmitted in compressed form.
It is most useful for web asset pipelines, map layers, and technical graphics repositories where vector fidelity matters and pre-compressed files are already part of the deployment model.
If the downstream environment already applies gzip or brotli to ordinary SVG responses, plain SVG is often easier to work with.
Choose SVGZ when the consumer explicitly expects it or when archived asset size is worth prioritizing.

What should I review after converting NUMBERS to SVGZ?
Check the exported file for Not human-readable without decompression.; Requires correct HTTP headers for web delivery.; Cannot be edited directly — must decompress first..
