libxlsxwriter: Reporting Bugs

Here are some tips on reporting bugs in libxlsxwriter.

Upgrade to the latest version of the library

Upgrade to the latest version of the library since the bug you are reporting
may already be fixed.

Check the Changes section of the documentation to see what has
changed in the latest versions.

You can check which version of libxlsxwriter that you are using by checking
the xlsxwriter.h header file or by adding the following to your program:

#include <stdio.h>
#include "xlsxwriter.h"

int main() {

    printf("Libxlsxwriter version = %s\n", lxw_version());

    return 0;
}

Read the documentation

Read or search the libxlsxwriter documentation to see if the issue
you are encountering is already explained.

Look at the example programs

There are many examples programs in the distribution. Try to
identify an example program that corresponds to your query and adapt it to use
as a bug report.

Tips for submitting a bug report

Describe the problem as clearly and as concisely as possible.
Include a sample program. This is probably the most important step.
It is generally easier to describe a problem in code than in written
prose.
The sample program should be as small as possible to demonstrate the
problem. Don't copy and paste large non-relevant sections of your
program.

A sample bug report is shown below. This format helps analyze and respond to
the bug report more quickly.

Subject: Issue with SOMETHING

Greetings,

I am using libxlsxwriter to do SOMETHING but it appears to do SOMETHING ELSE.

I am using CC version X.Y.Z, OS = uname and libxlsxwriter x.y.z.

Here is some code that demonstrates the problem:
#include "xlsxwriter.h"

int main() {

   lxw_workbook  *workbook  = workbook_new("bug_report.xlsx");
   lxw_worksheet *worksheet = workbook_add_worksheet(workbook, NULL);

   worksheet_write_string(worksheet, 0, 0, "Hello", NULL);
   worksheet_write_number(worksheet, 1, 0, 123, NULL);

   return workbook_close(workbook);
}

tip: error creating output xlsx file. Usually a permissions error.

@jmcnamara commented on GitHub (Jan 17, 2024):

That error happens for several possible reasons that aren't related to libxlsxwriter:

The directory you are writing to doesn't exist.
You don't have permissions to write to the target directory.
On Windows, the file is already open in Excel.
