Document conversion is the process of changing a file from one format to another. This can involve transforming text documents, spreadsheets, or presentations into different formats, such as converting a PDF file into a Word document or changing an Excel spreadsheet into a CSV file. The goal is to make the document compatible with various software applications or to facilitate easier sharing and editing. This process is often used in business and education to ensure that documents can be accessed and utilized by different users and systems. Document conversion tools and software can automate this process, saving time and reducing errors.
