If any one give some link or any guidance it will really help me to come out of my importing of data from excel to mysql problem.
This is best plugin with proper documentation and examples
Use output buffering to save your phpexcel output into a variable as per How do I write my excel spreadsheet into a variable, using PhpExcel?
And then store the output into a MySQL BLOB. I don't think you'd need to serialize it, but look into what needs to happen depending on what MySQL tells you and report back to us :)
