When using File Optimization, 3 common question types come up most often: data impact, processing time, and recovery options; this FAQ also includes a short glossary.
FAQ
Will File Optimization affect spreadsheet data?
- File Optimization is mainly used to clean redundant data, cache items, and other optimizable content.
- Under normal use, the actual spreadsheet content is not rewritten by the optimization process.
- If the file is important, save a backup copy before running optimization.
How long does File Optimization take?
- Processing time depends on the file size and complexity.
- Small files usually finish faster, while large files or files with many pictures can take longer.
- Wait until optimization is complete before saving, sharing, or continuing to edit.
Does File Optimization work for cloud files in collaboration mode?
- File Optimization is designed for collaborative spreadsheet scenarios.
- After optimization, the file size can be reduced to support later opening and collaboration.
- If the file needs ongoing sync, run the operation when the network connection is stable.
What can I do if the optimization result is not ideal?
- First check whether you saved a backup version before optimization.
- If the file supports version history, try returning to an earlier version.
- Before running optimization again, review your picture compression and file maintenance needs.

| Term | Definition |
|---|---|
| File Optimization | A process that reduces file size, usually by compressing pictures and cleaning redundant data, styles, or cache items. |
| Redundant data | Extra data or leftover content in a file that adds size but has limited value for current use. |
| Automatic optimization | A setting that allows file optimization to run automatically when a file meets the required conditions after opening. |
