example of converting nested objects {sheet>column>row} input from json format into excel format
from hfexcel import HFExcel
from hfexcel.schemas import DEFAULT_SCHEMA

excel_data = {
"sheets": [
{
"key": "sheet1",
"name": "Example Sheet 1",
"columns": [
{
"name": "Column 1",
"width": 2,
"args": [
"headline"
],
"rows": [
{
"data": "Column 1 Row 1"

},
{
"data": "Column 1 Row 2"
}
]
},
{
"name": "Column 2",
"rows": [
{
"data": "Column 2 Row 1",
},

"data": "Column 2 Row 2",
}

hf_workbook = HFExcel.hf_workbook('example.xlsx', set_default_styles=False)

example of object-oriented python syntax
from hfexcel import HFExcel

hf_workbook = HFExcel.hf_workbook('example.xlsx', set_default_styles=False)

hf_workbook.add_style(
"headline",
{
"bold": 1,
"font_size": 14,
"font": "Arial",
"align": "center"
}
)

sheet1 = hf_workbook.add_sheet("sheet1", name="Example Sheet 1")

column1, _ = sheet1.add_column('headline', name='Column 1', width=2)
column1.add_row(data='Column 1 Row 1')
column1.add_row(data='Column 1 Row 2')

column2, _ = sheet1.add_column(name='Column 2')
column2.add_row(data='Column 2 Row 1')
column2.add_row(data='Column 2 Row 2')

column3, _ = sheet1.add_column(name='Column 3')
column3.add_row(data='Column 3 Row 1')
column3.add_row(data='Column 3 Row 2')

# In order to get a row with coordinates:
# sheet[column_index][row_index] => row
print(sheet1[1][1].data)
assert(sheet1[1][1].data == 'Column 2 Row 2')

hf_workbook.save()

example of converting inline index-based {sheet>[column:row]} input from json format into excel format

"rows": [
[
{
"data": "Column 1 Row 1"

},
{
"data": "Column 2 Row 1"
}
],
[
{
"data": "Column 1 Row 2"

},
{
"data": "Column 2 Row 2"
}
]
]

{
"name": "headline",
"style": {
"bold": 1,
"font_size": 14,
