Excel Compressor
Shrink oversized workbooks without losing data.
Reduce file size by recompressing the package, downsampling embedded images, dropping cached pivot data and removing unused styles. Every option shows the bytes it will save before you apply it, and your data is never altered.

Common problems and fixes
Barely any size reduction.
The file is genuinely data-heavy. Check the breakdown — if sheet XML dominates, the answer is fewer rows or fewer sheets, not compression.
Pivot tables show no data after compressing.
Their cache was dropped. Hit Refresh All in Excel and they repopulate from the source range.
