Why pylightxl over pandas/openpyxl/xlrd

• Zero non-standard library dependencies No compatibility/version control issues.

• Light-weight single source code file that supports both Python3 and Python2.7.18. Single source file that can easily be copied directly into a project for true zero-dependency. Great for those that have installation/download restrictions. In addition the library's size and zero dependency makes this library pyinstaller compilation small and easy!

• 100% test-driven development for highest reliability/maintainability with 100% coverage on all supported versions

• API aimed to be user friendly and intuitive. Structure: database > worksheet > indexing example: db.ws('Sheet1').index(row=1,col=2) or db.ws('Sheet1').address(address='B1')

pypi version 1.47

• added new function: db.nr('table1') returns the contents of named range "table1"
• added new function: db.ws('Sheet1').range('A1:C3') that returns the contents of a range it also has the ability to return the formulas of the range
• updated db.ws('Sheet1').row() and db.ws('Sheet1').col() to take in a new argument formual that returns the formulas of a row or col
• bugfix: write to existing without named ranges was throwing a "repair" error. Fixed typo on xml for it and added unit tests to capture it
• added new function: xl.readcsv(fn, delimiter, ws) to read csv files and create a pylightxl db out of it (type converted)
• added new function: xl.writecsv(db, fn, ws, delimiter) to write out a pylightxl worksheet as a csv
