# How to convert an HTML table to JSON

To convert an HTML table to JSON:

1. Store the values of the th elements in an array.
2. Store the values of the td elements in an array.
3. Concatenate the two arrays and use the JSON.stringify() method.

Here is the HTML for the example.

Copied! 
DOCTYPE html> html lang="en"> head> meta charset="UTF-8" /> head> body> div class="box">bobbyhadz.comdiv> br /> br /> br /> table id="my-table"> thead> tr> th>Col 1th> th>Col 2th> th>Col 3th> tr> thead> tbody> tr> td>A1td> td>A2td> td>A3td> tr> tr> td>B1td> td>B2td> td>B3td> tr> tr> td>C1td> td>C2td> td>C3td> tr> tbody> table> script src="index.js"> script> body> html> 

And here is the code for the index.js file.

Copied! 
function toObject(table)  const thead = Array.from(table.tHead.rows[0].children).map( el => el.textContent, ); const tbody = Array.from(table.tBodies[0].rows).map(row => Array.from(row.cells).map(cell => cell.textContent), ); return  table: [thead].concat(tbody), thead, tbody, >; > const table = document.getElementById('my-table'); const obj = toObject(table); // 👇️ [['Col 1','Col 2','Col 3'],['A1', 'A2', 'A3'], ['B1', 'B2', 'B3'], ['C1', 'C2', 'C3']] console.log(obj.table); // 👇️ ['Col 1', 'Col 2', 'Col 3'] console.log(obj.thead); // [['A1', 'A2', 'A3'], ['B1', 'B2', 'B3'], ['C1', 'C2', 'C3']] console.log(obj.tbody); const jsonStr = JSON.stringify(obj.table); // [["Col 1","Col 2","Col 3"],["A1","A2","A3"],["B1","B2","B3"],["C1","C2","C3"]] console.log(jsonStr); 

The toObject function converts the table to an object that has 3 properties:

Copied! 
// 👇️ [['Col 1','Col 2','Col 3'],['A1', 'A2', 'A3'], ['B1', 'B2', 'B3'], ['C1', 'C2', 'C3']] console.log(obj.table); 

Copied! 
// 👇️ ['Col 1', 'Col 2', 'Col 3'] console.log(obj.thead); 

Copied! 
// [['A1', 'A2', 'A3'], ['B1', 'B2', 'B3'], ['C1', 'C2', 'C3']] console.log(obj.tbody); 

If you need to convert any of the properties to JSON, use the JSON.stringify method.

Copied! 
const jsonStr = JSON.stringify(obj.table); // [["Col 1","Col 2","Col 3"],["A1","A2","A3"],["B1","B2","B3"],["C1","C2","C3"]] console.log(jsonStr); 

# How to convert an HTML table to an Array of Objects

If you need to convert the HTML table to an array of objects:

1. Get an array of the table’s headings.
2. Get an array of the table’s rows.
3. Iterate over the table’s rows and store each heading as a key and the current th text content as the value.

The HTML for the example is the same as in the previous subheading.

Copied! 
DOCTYPE html> html lang="en"> head> meta charset="UTF-8" /> head> body> div class="box">bobbyhadz.comdiv> br /> br /> br /> table id="my-table"> thead> tr> th>Col 1th> th>Col 2th> th>Col 3th> tr> thead> tbody> tr> td>A1td> td>A2td> td>A3td> tr> tr> td>B1td> td>B2td> td>B3td> tr> tr> td>C1td> td>C2td> td>C3td> tr> tbody> table> script src="index.js"> script> body> html> 

Here is the related JavaScript code.

Copied! 
function toArrayOfObjects(table)  const columns = Array.from(table.querySelectorAll('th')).map( heading => heading.textContent, ); const rows = table.querySelectorAll('tbody > tr'); return Array.from(rows).map(row =>  const dataCells = Array.from(row.querySelectorAll('td')); return columns.reduce((obj, column, index) =>  obj[column] = dataCells[index].textContent; return obj; >, >); >); > const table = document.getElementById('my-table'); // [ // // "Col 1": "A1", // "Col 2": "A2", // "Col 3": "A3" // >, // // "Col 1": "B1", // "Col 2": "B2", // "Col 3": "B3" // >, // // "Col 1": "C1", // "Col 2": "C2", // "Col 3": "C3" // > // ] console.log(toArrayOfObjects(table)); const jsonStr = JSON.stringify(toArrayOfObjects(table)); // [,,] console.log(jsonStr); 

The toArrayOfObjects() function takes a table element as a parameter and returns an array of objects.

The table headings are used as properties in each object and the text content of the td elements is used as the values.

If you need to convert the array of objects to a JSON string, use the JSON.stringify() method.

# Convert an HTML table to JSON and export it as a JSON file

1. Converts the HTML table to a JSON array of objects (could be any other data structure).
2. Exports the JSON to a file.

Here is the HTML for the example.

Copied! 
DOCTYPE html> html lang="en"> head> meta charset="UTF-8" /> head> body> div class="box">bobbyhadz.comdiv> br /> br /> br /> table id="my-table"> thead> tr> th>Col 1th> th>Col 2th> th>Col 3th> tr> thead> tbody> tr> td>A1td> td>A2td> td>A3td> tr> tr> td>B1td> td>B2td> td>B3td> tr> tr> td>C1td> td>C2td> td>C3td> tr> tbody> table> button id="btn">Click to Download Table as JSONbutton> script src="index.js"> script> body> html> 

And here is the code for the index.js file.

Copied! 
function toArrayOfObjects(table)  const columns = Array.from(table.querySelectorAll('th')).map( heading => heading.textContent, ); const rows = table.querySelectorAll('tbody > tr'); return Array.from(rows).map(row =>  const dataCells = Array.from(row.querySelectorAll('td')); return columns.reduce((obj, column, index) =>  obj[column] = dataCells[index].textContent; return obj; >, >); >); > const table = document.getElementById('my-table'); function downloadJSONTable(jsonStr, fileName)  const dataStr = `data:text/json;charset=utf-8,$encodeURIComponent( jsonStr, )>`; const anchorElement = document.createElement('a'); anchorElement.href = dataStr; anchorElement.download = `$fileName>.json`; document.body.appendChild(anchorElement); anchorElement.click(); document.body.removeChild(anchorElement); > const downloadButton = document.getElementById('btn'); downloadButton.addEventListener('click', () =>  const jsonStr = JSON.stringify(toArrayOfObjects(table)); downloadJSONTable(jsonStr, 'myFile'); >); 

Here are the contents of the exported .json file.

The downloadJSONTable function takes a JSON string and the name the downloaded file should have on the user’s file system as parameters and exports the supplied JSON string to a file.

The file is a bit difficult to read because it only consists of a single line, however, you could pretty print the JSON by passing a third argument to the JSON.stringify() method.

Copied! 
const jsonStr = JSON.stringify( toArrayOfObjects(table), null, 2, ); 

The third argument is the indentation of the JSON string.

The new JSON string is much more readable as each key-value pair is displayed on a separate line.
