A1 notation converter
The A1 notation converter library allows the user to convert integer to its A1 notation form and vice versa. In this context, the A1 notation refer to the syntax used in spreadsheet program such as Google Sheets and Microsoft Excel to represent the index of column within the spreadhseet.
E.g. 'G' represents 7th column, 'AZ' represents 52th column.
Version 1.0.9
- Fixed logic error in function 'int_to_a1()' where number value from 52 does not modulo and divide properly to output the correct A1 notation. E.g.
int_to_a1(52) # return "B@" (should be "AZ")
int_to_a1(78) # return "C@" (should be "BZ")
- Added unit testing to validate function behaviour.
Installation
Installation of this library can be done with Python pip:
pip install a1-notation-converter
The package and release history can be found at pypi.org.
Example
Importing the library:
from a1_notation_converter import a1_converter
Converting integer to A1 notation:
a1_converter.int_to_a1(1) # return "A"
a1_converter.int_to_a1(27) # return "AA"
a1_converter.int_to_a1(731) # return "ABC"
Converting A1 notation to integer:
a1_converter.a1_to_int("A") # return 1
a1_converter.a1_to_int("AA") # return 27
a1_converter.a1_to_int("CBA") # return 2081
