Where to start? I use Mathematica extensively to do data analysis and modeling. But I have never used Mathematica for data entry. Once I get the data in some electronic format, I typically use a text editor to format the files as a Mathematica expression putting comments at the start of each data file. That is the structure of the files are typically: (* comments *) { {field1, field2 . .... fieldn},
