Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores tabular data (numbers and text) in plain text, where each line of the file typically represents one data record. Each record consists of the same number of fields, and these are separated by commas in the ...
Pandas (styled as pandas) is a software library written for the Python programming language for data manipulation and analysis. In particular, it offers data structures and operations for manipulating numerical tables and time series .
[2]: 113 Column headers are sometimes included as the first line, and each subsequent line is a row of data. The lines are separated by newlines . For example, the following fields in each record are delimited by commas, and each record by newlines:
Tab-separated values (TSV) is a simple, text-based file format for storing tabular data. [3] Records are separated by newlines, and values within a record are separated by tab characters.
The pandas package in Python implements this operation as "melt" function which converts a wide table to a narrow one. The process of converting a narrow table to wide table is generally referred to as "pivoting" in the context of data transformations.
Column labels are used to apply a filter to one or more columns that have to be shown in the pivot table. For instance if the "Salesperson" field is dragged to this area, then the table constructed will have values from the column "Sales Person", i.e., one will have a number of columns equal to the number of "Salesperson". There will also be ...
Set the file type to Excel before printing. Rename the extension of the resulting file from PRN to CSV. Use this XL2QIF Excel macro to convert to QIF. The Excel file may need to be reorganized to generate the appropriate format for the macro to work, such as separating cheque accounts from term deposits, etc.
