How to Convert CSV to Excel 2010

The Excel 2010 file format, .xlsx, is capable of storing multiple sheets within the workbook that you have created.

Using multiple sheets in one workbook is the ideal solution when you have a lot of different spreadsheets that are all related to the same topic and you want to access all of that data without needing to open a bunch of different files.

CSV files, on the other hand, are essentially text files where the cells, columns and rows are separated by a delimiter, such as a comma.

These are very popular file types because of their diversity and compatibility with a number of different files. Excel 2010 is compatible with CSV files, and will open them the same way that it would open an .xlsx file.

However, CSV files only have one sheet and, if you attempt to save a CSV file in Excel, it will save as a CSV file unless you manually adjust the file type.

So you can use Excel 2010 to convert your CSV file or, if you do not have Excel 2010, you can use an online converter to turn the file into the .xlsx file type.

How to Convert a CSV File to XLSX With Excel 2010

Excel 2010 is a very versatile program, and can open almost any type of file format that produces spreadsheet-like information.

Additionally, once the file is open in Excel, it is also rather simple to convert the file to any other type of file that Excel can create.

However, Excel does not choose a default file format, but rather will attempt to keep the file in the same format that it started with. In some cases with a CSV file that will not be possible.

For instance, if you open a CSV file in Excel 2010 but add a second sheet to it, you will get a warning when saving the file as a CSV that the file format is not compatible with multiple worksheets, and you can choose whether you only want to save the active sheet as a CSV or if you want to choose a different file format.
