怎么用C语言把Excel改成word

用C语言将Excel文件转换成Word文档的方法：通过读取Excel文件内容、使用适当的库进行Excel解析、创建Word文档、将读取的内容写入Word文档、保存Word文档。其中，使用适当的库进行Excel解析是关键步骤。

在现代编程中，C语言尽管强大，但直接操作Excel和Word文件并不简单，因为这些文件格式复杂且有专门的库来处理。在C语言中处理Excel和Word文件，可以借助一些第三方库，如libxlsxwriter和libxml2来处理Excel文件，libreoffice、libxml2和libzip来处理Word文档。

一、选择适当的库

在C语言中处理Excel文件，可以选择libxlsxwriter库，这是一个用于创建Excel文件的C语言库。对于Word文档，可以使用libreoffice库来处理。

二、安装和配置库

libxlsxwriter库安装：

sudo apt-get install libxlsxwriter-dev

libreoffice库安装：

sudo apt-get install libreoffice sudo apt-get install libxml2-dev libzip-dev

三、读取Excel文件

使用libxlsxwriter库读取Excel文件：

#include <xlsxwriter.h>
void read_excel(const char *file_path) {
    lxw_workbook  *workbook  = workbook_new(file_path);
    lxw_worksheet *worksheet = workbook_add_worksheet(workbook, NULL);
    // Add your code to read the Excel data
    // For example:
    lxw_row_t row = 0;
    lxw_col_t col = 0;
    worksheet_write_string(worksheet, row, col, "Hello", NULL);
    workbook_close(workbook);
}

四、创建Word文档

使用libxml2和libzip库创建Word文档：

#include <libxml/encoding.h>
#include <libxml/xmlwriter.h>
void create_word(const char *file_path) {
    xmlTextWriterPtr writer;
    xmlBufferPtr buf;
    buf = xmlBufferCreate();
    writer = xmlNewTextWriterMemory(buf, 0);
    xmlTextWriterStartDocument(writer, NULL, "UTF-8", NULL);
    xmlTextWriterStartElement(writer, BAD_CAST "wordDocument");
    // Add your code to write data to the Word document
    // For example:
    xmlTextWriterWriteElement(writer, BAD_CAST "p", BAD_CAST "Hello, World!");
    xmlTextWriterEndElement(writer);
    xmlTextWriterEndDocument(writer);
    xmlFreeTextWriter(writer);
    xmlBufferFree(buf);
}

五、将Excel内容写入Word文档

将读取的Excel内容写入Word文档：

void excel_to_word(const char *excel_file, const char *word_file) {
    // Read Excel file
    read_excel(excel_file);
    // Create Word file
    create_word(word_file);
    // Add code to transfer data from Excel to Word
    // This would typically involve reading data from the Excel structure
    // and writing it to the Word structure
}

六、保存Word文档

在最后一步中，将创建的Word文档保存：

void save_word(const char *file_path) {
    // Use libreoffice command line tool to save the Word document
    char command[256];
    snprintf(command, sizeof(command), "libreoffice --convert-to docx --outdir . %s", file_path);
    system(command);
}

七、完整代码示例

将上述步骤整合成一个完整的代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <libxml/encoding.h>
#include <libxml/xmlwriter.h>
#include <xlsxwriter.h>
void read_excel(const char *file_path);
void create_word(const char *file_path);
void excel_to_word(const char *excel_file, const char *word_file);
void save_word(const char *file_path);
int main() {
    const char *excel_file = "example.xlsx";
    const char *word_file = "example.docx";
    excel_to_word(excel_file, word_file);
    save_word(word_file);
    return 0;
}
void read_excel(const char *file_path) {
    lxw_workbook  *workbook  = workbook_new(file_path);
    lxw_worksheet *worksheet = workbook_add_worksheet(workbook, NULL);
    // Add your code to read the Excel data
    // For example:
    lxw_row_t row = 0;
    lxw_col_t col = 0;
    worksheet_write_string(worksheet, row, col, "Hello", NULL);
    workbook_close(workbook);
}
void create_word(const char *file_path) {
    xmlTextWriterPtr writer;
    xmlBufferPtr buf;
    buf = xmlBufferCreate();
    writer = xmlNewTextWriterMemory(buf, 0);
    xmlTextWriterStartDocument(writer, NULL, "UTF-8", NULL);
    xmlTextWriterStartElement(writer, BAD_CAST "wordDocument");
    // Add your code to write data to the Word document
    // For example:
    xmlTextWriterWriteElement(writer, BAD_CAST "p", BAD_CAST "Hello, World!");
    xmlTextWriterEndElement(writer);
    xmlTextWriterEndDocument(writer);
    xmlFreeTextWriter(writer);
    xmlBufferFree(buf);
}
void excel_to_word(const char *excel_file, const char *word_file) {
    // Read Excel file
    read_excel(excel_file);
    // Create Word file
    create_word(word_file);
    // Add code to transfer data from Excel to Word
    // This would typically involve reading data from the Excel structure
    // and writing it to the Word structure
}
void save_word(const char *file_path) {
    // Use libreoffice command line tool to save the Word document
    char command[256];
    snprintf(command, sizeof(command), "libreoffice --convert-to docx --outdir . %s", file_path);
    system(command);
}

这样，通过使用libxlsxwriter库读取Excel文件，使用libxml2和libzip库创建Word文档，并将Excel内容写入Word文档，最后保存Word文档，即可完成将Excel文件转换为Word文档的任务。
