openpyxl導致excel中現有的DataValidation丟失

Question

我正在使用openpyxl導入現有的excel表格並試圖填充一些值並重新保存，但我注意到這樣做時電子表格中現有的Data Validation下拉框會搞砸。即使只是加載電子表格，不做任何其他操作，然後重新保存，也會發生這種情況，所以它似乎是openpyxl的內在特性。電子表格中的數據驗證由某些單元格中的Dropbox組成，這些單元格從大約20列以上的其他單元格中獲取可能值（這是爲公司生成QC報告）。例如，單元格C13具有$ Z $ 6：$ AB $ 6的初始數據有效性「源」，但是在加載並保存Excel表格後，該單元格會錯誤地更改爲$ Z $ 5：$ AB $ 5。奇怪的是，這在所有單元格中並不一致;一些細胞保持在正確的範圍內，而一些細胞卻是五行左右。它看起來像只有行，而不是列。所有包含數據驗證的單元格都會合並，我不確定是否重要。有誰知道爲什麼會發生這種情況，或者如何解決這個問題？沒有太多的代碼來顯示，但這裏是一個負載的一個簡單例子/保存功能，這將導致此問題：

wb = load_workbook(filename='myspreadsheet.xlsx') 
    wb.save('myspreadsheet.xlsx') 

提前感謝！ Robert

Answer 1

這可能是因爲您的Excel表格有重疊單元格範圍定義的數據驗證，導致openpxyl和/或excel混淆。

當使用此代碼：

wb = load_workbook(filename='DataValidationErrorExample.XLSX') 
ws = wb.worksheets[0] 
print(ws.data_validations) 

我得到：

的sqref屬性顯示的數據驗證適用的細胞，你可以看到有不同的之間有一些重疊數據驗證。
