Python轻松实现删除Excel工作表中的空白行列

pip install spire.xls

from spire.xls import Workbook

# 创建工作簿对象
workbook = Workbook()
# 加载已有 Excel 文件
workbook.LoadFromFile("sample.xlsx")
# 选择第一个工作表
sheet = workbook.Worksheets[0]

# 获取行数
row_count = sheet.LastRow

# 从最后一行开始向上遍历
for row in range(row_count, 0, -1):
    is_empty = True
    for col in range(1, sheet.LastColumn + 1):
        if sheet.Range[row, col].Value is not None and sheet.Range[row, col].Value != "":
            is_empty = False
            break
    if is_empty:
        sheet.DeleteRow(row)

# 保存修改后的文件
workbook.SaveToFile("cleaned.xlsx")

# 获取列数
col_count = sheet.LastColumn

# 从最后一列开始向前遍历
for col in range(col_count, 0, -1):
    is_empty = True
    for row in range(1, sheet.LastRow + 1):
        if sheet.Range[row, col].Value is not None and sheet.Range[row, col].Value != "":
            is_empty = False
            break
    if is_empty:
        sheet.DeleteColumn(col)

# 保存修改后的文件
workbook.SaveToFile("cleaned.xlsx")

for sheet in workbook.Worksheets:
    # 删除空白行
    for row in range(sheet.LastRow, 0, -1):
        if all(sheet.Range[row, col].Value in (None, "") for col in range(1, sheet.LastColumn + 1)):
            sheet.DeleteRow(row)

    # 删除空白列
    for col in range(sheet.LastColumn, 0, -1):
        if all(sheet.Range[row, col].Value in (None, "") for row in range(1, sheet.LastRow + 1)):
            sheet.DeleteColumn(col)

workbook.SaveToFile("cleaned_all_sheets.xlsx")

if sheet.Range[row, col].Value and sheet.Range[row, col].Value.strip() != "":
    is_empty = False
