Hello, I am working on a project and I need to read and write and read etc in file.xlsx. I use a C programm on Windows with the lib xlsxio. I try to use the lib xlsxio, but when I want to write, the lib empty my file.xlsx (or delete or overwrite the file) before write but I want to keep the content of the original/older file. I saw this comment in the exemple :( //open .xlsx file for writing (will overwrite if it already exists) Is-it possible to write and keep the old content of the file? (I have many data in the original file, it will be complicated to save all the content in the C programm). Thank you for the help Thomas

XLSX I/O aims to be a library to read from / write to .xlsx files in a streaming fashion. If you need to edit .xlsx files in place then you should check out other libraries that may better suit your needs.
