node-red-buffer-xlsx

A simple node-red node for converting JSON to a buffered xlsx. This package uses the node package better-xlsx.

Usage

To ensure the node works correctly the JSON has to be formatted in a certain way. All styling options are optional.

Sheet Formatting

The JSON can consist of multiple sheets, these are the properties each sheet can have:

sheet_name
sheet_styling
header_styling
columns_styling
rows

sheet_name (required): This is the name the sheet shall receive at the bottom.

sheet_styling (optional): Styling for the entire sheet, see Styling Formats

header_styling (optional): Styling for the header row, see Styling Formats

columns_styling (optional): columns_styling should be an array of object with the following info:
- index
- column_styling
  
  index: The column you want to apply the styling to starting at 0
  
  column_styling: See Styling Formats
rows (required): See Row Formatting.

Sheet Example:

[
 {
   "sheet_name": "sheet1",
   "sheet_styling": {
     "hAlign": "center",
     "fSize": "11"
   },
   "header_styling": {
     "fBold": true
   },
   "columns_styling": [
     {
       "index": 0,
       "column_styling": {
         "fItalic": true
       }
     }
   ],
   "rows": [
     {
       // See # Row Formatting
     }
   ]
 }
]

Row Formatting

The JSON can consist of multiple rows, these are the properties each row can have:

row_styling
cells

row_styling (optional): Styling for the entire row, see Styling Formats

cells (required): See Cell Formatting.

Row Example:

"rows": [
  {
    "row_styling": {

      {
        // See # Cells Formatting
      }
    ]
  }
]

Cell Formatting

The JSON can consist of multiple cells, these are the properties each cell can have:

cell_value
cell_styling

cell_value (optional): Value that will be displayed in the cell

cell_styling (optional): Styling for single cell, see Styling Formats.
