SVM is applicable only for numeric data or can also be for textual data?
SVM can work with textual data also. However you have to train the SVM to classify the text data. It is a usual practice to create a document-term matrix from the text that you have, to make SVM work easily on the data.

Main problem statement : import a .xlsx file in python with a dataset value then after import we need to ensure that every time I enter a value in a row ; row must be added by 1 and automatically value changes to a row using python script without manually intervention .
Use read_csv in a loop, there's no other way for this.
