Data parser
Bootstrap 5 Data parser plugin
Data Parser is a custom react hook which helps to display your data (.json, .csv) in MDB5 components.
It returns parser object that has a parse() method which can transform your data based on selected
options into the required format and set of useful functions for more complicated data
operations.
Note: Read the API tab to find all available options and advanced customization
Datatable
CSV
When parsing CSV into Datatables format (rows and columns), by default all lines are treated
as rows (there is no header included). You can change that by setting
headerIndex to the position of a header row.
You can customize both columns and rows (values between start/end or only selected indexes).
Note: When you set a headerIndex, remember to exclude this
value from rows (for example by setting rows.start to a next index).
Data used in this example: Population Figures
import { useMDBDataParse } from 'mdb-react-data-parser';
import { MDBDatatable } from 'mdb-react-ui-kit';
import React, { useEffect, useState } from 'react';
export default function App() {
const [rows, setRows] = useState<any>([]);
const { parser } = useMDBDataParse('datatable', 'csv', {
rows: { start: 10, end: 14 },
columns: {
indexes: [0, 1, 57, 58],
},
});
useEffect(() => {
fetch('/csv_datatable.csv')
.then((data) => data.text())
.then((data) => {
const { rows } = parser.parse(data);
setRows(rows);
});
}, []);
return (
<MDBDatatable
data={{
columns: ['Country', 'Code', 'Population 2015', 'Population 2016'],
rows,
}}
/>
);
};
JSON
You can define options for rows in exactly the same way as in CSV format
(start, end / indexes). Instead of doing the same for columns, provide an array of selected
keys to the keys options.
Data used in this example: Population Figures
import { useMDBDataParse } from 'mdb-react-data-parser';
import { MDBDatatable } from 'mdb-react-ui-kit';
import React, { useEffect, useState } from 'react';
const columns = [
{ label: 'Country', field: 'Country' },
{ label: 'Code', field: 'Country_Code' },
{ label: 'Population 2015', field: 'Year_2015' },
{ label: 'Population 2016', field: 'Year_2016' },
];
export default function App() {
const [rows, setRows] = useState<any>([]);
const { parser } = useMDBDataParse('datatable', 'json', {
rows: { start: 30, end: 100 },
keys: columns.map((columns) => columns.field),
});
useEffect(() => {
fetch('/json_datatable.json')
.then((data) => data.json())
.then((data) => {
const { rows } = parser.parse(data);
setRows(rows);
});
}, []);
return (
<MDBDatatable
data={{
columns,
rows,
}}
/>
);
};
Vector Maps
CSV
Creating a colorMap based on a CSV Data requires identifying the region - Vector Maps uses alpha2Code for IDs, which isn't always convenient. Data Parser can, in most cases, fetch the required identifier based on the country's name or alpha3Code.
Note: If you don't set the step option to a fixed value, Data
Parser will compute equal size intervals - it may resolve in empty intervals if values are
unevenly distributed.
Data used in this example: Population Figures
import { useMDBDataParse } from 'mdb-react-data-parser';
import { MDBVectorMap } from 'mdb-react-vector-maps';
import React, { useEffect, useState } from 'react';
export default function App() {
const [data, setData] = useState<any>([]);
const { parser } = useMDBDataParse('vectorMap', 'csv', {
color: 'lightGreen',
field: 42,
rows: {
start: 1,
},
step: 8000000,
countryIdentifier: 1,
});
useEffect(() => {
fetch('/csv_vector.csv')
.then((data) => data.text())
.then((data) => {
const { colorMap } = parser.parse(data);
setData(colorMap);
});
}, []);
return <MDBVectorMap readonly fill='white' hover={false} colorMap={data} />;
};
JSON
Apart from a colorMap, parse() method returns also a legend based on which you
can easily display value-color corelations.
If you're not satisfied with colors available out of the box, you can pass an array of color strings based on which DataParser will create your colorMap.
The getCoordinates() method helps to find x and y map coordinates based on
longitude and latitude.
Calculated point is an approximation and might not be accurate.
Data used in this example: Population Figures
Population (2016):
import { useMDBDataParse } from 'mdb-react-data-parser';
import { MDBVectorMap } from 'mdb-react-vector-maps';
import React, { useEffect, useState } from 'react';

Charts
CSV
Creating datasets for your Chart component requires two kinds of labels - labels for each
specific dataset (datasetLabel: column's index) as well as labels for data
points (labelsIndex: index of a row with labels).
Additionally, you can format the datasetLabel using
formatLabel option.
Note: Data Parser generates a color for each dataset, which you can later
use for background/border color. By default, values comes from mdb palette but
you can also use
full palette
- in this case the color option's value should refer to the intensity (from 50
to 900).
Basic data
Suitable for most of the chart types (line, bar, horizontal bar, radar, polar, doughnut, pie)

Treeview
Using the Treeview requires defining name and children properties in your objects - as it can be an inconvenience, Data Parser allows pointing to other fields as their equivalent (f.e. name -> title, children -> content).
In the same time, you can still make use of other properties (icon, disabled, show) which are not typically defined in data structures. Each of them is a function which takes an object as its argument and returns a field's value depending on your custom logic.
JSON
Note: CSV format is not available for the Treeview component.
