Sheet Zipper for Windows
Your workbook.
Your computer.
Analyze, optimize, archive, and restore complex Excel workbooks locally—with integrity checks built into every output.
XLSXModern workbooks
XLSMMacro-enabled files
XLSBBinary workbooks
XLZVerified archives
Four workflows
One careful toolkit.
Choose the operation you need. Sheet Zipper preserves the source and publishes a new output only after its checks pass.
OPTIMIZE
Reduce container overhead
Recompress workbook packages with Balanced or Maximum modes and keep the smaller verified result.
ARCHIVE + RESTORE
Store it as XLZ
Create a checksummed archive, then reconstruct and re-verify the workbook when it is needed again.
Private by architecture
No workbook uploads.
Sheet Zipper reads the paths you choose and runs Analyze, Optimize, Archive, and Restore on your device. Workbook content, filenames, and analysis results are not intentionally sent to Evernivo.
Original files are never overwritten. Temporary work is isolated, interrupted jobs are not silently resumed, and final outputs appear only after validation.
