要将PDF文件转换为TXT文件或docx文件,我建议你使用Python库来完成此任务。以下是一些常用的库和方法:
-
使用pdfminer库:
-
首先,你需要安装pdfminer库。可以使用以下命令安装:
`pip install pdfminer.six `
接下来,你可以使用下面的代码将PDF文件转换为TXT文件:
`from pdfminer.converter import TextConverter from pdfminer.pdfinterp import PDFPageInterpreter from pdfminer.pdfinterp import PDFResourceManager from pdfminer.pdfpage import PDFPage from io import StringIO def convert_pdf_to_txt(path): rsrcmgr = PDFResourceManager() codec = 'utf-8' outfp = StringIO() laparams = LAParams() device = TextConverter(rsrcmgr, outfp, codec=codec, laparams=laparams) with open(path, 'rb') as fp: interpreter = PDFPageInterpreter(rsrcmgr, device) for page in PDFPage.get_pages(fp, check_extractable=True): interpreter.process_page(page) text = outfp.getvalue() device.close() outfp.close() return text pdf_path = 'path/to/pdf/file.pdf' txt_path = 'path/to/txt/file.txt' text = convert_pdf_to_txt(pdf_path) with open(txt_path, 'w', encoding='utf-8') as file: file.write(text) `

-
使用pytesseract库:
-
首先,你需要安装pytesseract库和tesseract OCR引擎。可以使用以下命令安装:
`pip install pytesseract`
还需要下载并安装tesseract OCR引擎,可以从以下链接获取:https://github.com/tesseract-ocr/tesseract/wiki
-
接下来,你可以使用下面的代码将PDF文件转换为TXT文件:
`import pytesseract from pdf2image import convert_from_path def convert_pdf_to_txt(pdf_path, txt_path): images = convert_from_path(pdf_path) text = '' for i, image in enumerate(images): temp_file = f'temp_page_{i}.jpg' image.save(temp_file) text += pytesseract.image_to_string(temp_file) os.remove(temp_file) with open(txt_path, 'w', encoding='utf-8') as file: file.write(text) pdf_path = 'path/to/pdf/file.pdf' txt_path = 'path/to/txt/file.txt' convert_pdf_to_txt(pdf_path, txt_path)`
-
-
使用python-docx库:
-
首先,你需要安装python-docx库。可以使用以下命令安装:
`pip install python-docx`
-
接下来,你可以使用下面的代码将PDF文件转换为docx文件:
`from pdfminer.converter import TextConverter from pdfminer.pdfinterp import PDFPageInterpreter from pdfminer.pdfinterp import PDFResourceManager from pdfminer.pdfpage import PDFPage from io import StringIO from docx import Document def convert_pdf_to_docx(pdf_path, docx_path): rsrcmgr = PDFResourceManager() codec = 'utf-8' outfp = StringIO() laparams = LAParams() device = TextConverter(rsrcmgr, outfp, codec=codec, laparams=laparams) with open(pdf_path, 'rb') as fp: interpreter = PDFPageInterpreter(rsrcmgr, device) for page in PDFPage.get_pages(fp, check_extractable=True): interpreter.process_page(page) text = outfp.getvalue() device.close() outfp.close() doc = Document() doc.add_paragraph(text) doc.save(docx_path) pdf_path = 'path/to/pdf/file.pdf' docx_path = 'path/to/docx/file.docx' convert_pdf_to_docx(pdf_path, docx_path) `
请注意,上述代码中的路径需要根据实际的PDF文件路径和输出文件路径进行修改。
