pyexcel-export is a wrapper around pyexcel, pyexcel-xlsx and openpyxl to read formatting (stylesheets) and update pre-existing files without destroying the stylesheets.
pyexcel-export also introduces two new exporting format, *.yaml and *.pyexcel.json, which is based on NoIndentEncoder. This allows you to edit the spreadsheet in you favorite text editor without being frustrated by automatically collapsed cells in Excel.
The "stylesheets" exported from Excel is in a very long base64 encoded format when exported to *.json or *.pyexcel.json, so exporting such to *.json is disabled by default.
As stylesheets copying works by openpyxl.worksheet.copier.WorksheetCopy, it may work only on values, styles, dimensions, and merged cells, but charts might not be supported.
You can install pyexcel-export via pip:
$ pip install pyexcel-export
or clone it and install it.
