[英]Reading an excel file from C
I used C program to write into an excel file and it worked for both (.xls & .xlsx) 我用C程序写入一个excel文件,它对(.xls和.xlsx)都有效
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char const *argv[])
{
FILE * fpointer;
fpointer = fopen ("cfile.xls","w");
fprintf(fpointer, "Name \t MIT 801\t MIT 802\t MIT 803\t MIT 805\t MIT 821 \n Haphyz\t 90\t 89\t 99\t 95\t 96\n");
fclose(fpointer);
}
I also tried to read from it and it also worked: 我也尝试阅读它,它也起作用:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char const *argv[])
{
FILE * fpointer;
fpointer = fopen ("cfile.txt","r");
char Creader[200];
while (!feof(fpointer)){
fgets (Creader,200,fpointer);
puts (Creader);
}
fclose(fpointer);
return 0;
}
Now I'm trying to use C program to read an excel file that was created from the computer (not from C) but all I get is gibberish...nothing meaningful for both .xls and .xlsx
then I decided to use the .csv
format which worked but was only able to read only the first line of the excel sheet. 现在,我正在尝试使用C程序读取从计算机(不是从C)创建的excel文件,但是我得到的只是乱码...对于
.xls and .xlsx
都没有意义,所以我决定使用.csv
格式有效,但只能读取Excel工作表的第一行。 Please how do I go about this? 请我怎么做?
I have resolved the issue, the .csv
format works fine the problem was with my code. 我已经解决了这个问题,
.csv
格式可以很好地解决我的代码存在的问题。 I closed the file inside the loop so the program stops reading after the first line . 我在循环中关闭了文件,因此程序在第一行之后停止读取。
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char const *argv[])
{
FILE * fpointer;
fpointer = fopen("Book1.csv","r");
char spreadSheet[200];
while(!feof(fpointer)){
fgets(spreadSheet,200,fpointer);
fprintf(stderr, "%s\n", spreadSheet);
fclose(fpointer);
}
return 0;
}
There is no way this would return an error message ,so it printed out what I instructed it to . 这不可能返回错误消息,所以它打印出了我的指示。
Thanks for your contributions.I'll make sure to look at my code better next time 感谢您的贡献。下次,我将确保更好地查看我的代码
