VBA - 在PDF文件中查找文本，將其複製並粘貼到電子表格中

Question

我正在使用VBA自動將PDF文件中的文本提取到xls電子表格。

文本總是相同的「價格X」，「價格Y」，「價格Z」。

我需要在電子表格中查找，複製和粘貼它們。

有沒有人有我如何在VBA自動化這個過程的想法？

我還沒有找到相關的主題。

Answer 1

我認爲你最好的選擇是將PDF轉換爲文本文件（另存爲文本文件）並將文本文件導入Excel。

你可以谷歌如何做到這一點;這很容易，這將是一個偉大的學習練習。如果您還有其他問題，請發回。

Answer 2

如果您安裝了Adobe Acrobat，您可以將所有PDF文件轉換爲Excel文件。

除了主要程序，我還寫了一個循環，以便一次轉換多個PDF文件。所以，如果你有一個包含PDF文件的文件夾，你可以使用這個工具來獲取他們的文件路徑。然後，您可以使用附加的工作簿將其轉換爲不同的格式。該代碼實際上使用Adobe Professional的「另存爲」命令以將文件保存爲所需的格式。可用的格式是：

eps 
html and htm 
jpeg, jpg and jpe 
jpf, jpx, jp2, j2k, j2c and jpc 
docx 
doc 
png 
ps 
rft 
xlsx 
xls 
txt 
tiff and tif 
xml
