最近公司有用戶反映excel復制內容粘貼報錯“不同的單元格格式太多”，后來懷疑應該是樣式問題，一看樣式嚇了一跳，好多無用的樣式（如下圖）。
那就刪除樣式吧，可是怎么批量刪除呢，中文的搜索結果都沒搞定，那就試試英文的吧，還別說，與可行的解決方案，請往下看：
1. Rename your Excel workbook from .xlsx or .xlsm to .zip
2. Open the workbook with WinZip and navigate to xl folder
3. Right click on styles.xml and choose Open With Notepad
4. Hit Ctrl F to search for cellstyles (with the open XML tag mark in the front, can't make it show in the post）
5. Cancel out of the find dialogue box, move your cursor before cellstyles and hit enter twice (this is to mark where the beginning of this tag is)
6. Hit Ctrl F again and search for /cellstyles>
7. Highlight everything between step 5 and step 6 (everything in the cellstyles tags including the tags) and hit delete
8. Save the Notepad and exit Notepad. WinZip should now ask you whether to update the file. Select Update Zip file with changes. Hit OK and close out WinZip.
9. Rename the workbook zip file back to .xlsx or .xlsm
