Top 10 CSV Libraries in 2017

CSV stands for “comma separated values” which stores data in a tabular format. A comma separates the data fields and stores the data in a text file with extension “.csv”. CSV is a simple file format to save data in a tabular form such as spreadsheet or database.

  • CSV files can be used with any spreadsheet application, such as Microsoft Excel, Google Spreadsheets or Open Office.
  • The only difference from other spreadsheet file types is that it can only have a single sheet in a file and it can not save cell, column, or row styling, and formulas for different calculations.

In the programming world, Microsoft Excel is widely used to import/export data in different forms such as tables, charts, graphs, etc. There are a lot of libraries available which can read, write, convert and print spreadsheet files and the user can quickly add any of these libraries as per their requirements.
