Python module to convert JSON
into a human readable HTML Table
representation.
-
User friendly tabular format, easy to read and share.
-
If the value of the key is an array of objects and all the keys are the same (value of the key is a dict of a list), the module will club by default. E.g.:
input = { "sampleData": [{ "a":1, "b":2, "c":3 }, { "a":5, "b":6, "c":7 }] }
This will create only one row combining the results. This feature can be turned off by explicitly passing an argument
clubbing = False
. -
The generated table can have some
attributes
explicitly. E.g. giving anid
,class
, or anydata-*
attribute. -
Python 3 compatible.

json2html.convert
- The module's convert
method accepts the following arguments:
Argument | Description |
---|---|
json |
A valid JSON; This can either be a string in valid JSON format or a Python object that is either dict-like or list-like at the top level. |
table_attributes |
E.g. pass id="info-table" or class="bootstrap-class" /data-* to apply these attributes to the generated table. |
clubbing |
Turn on [default]/off clubbing of list with the same keys of a dict / Array of objects with the same key. |
encode |
Turn on/off [default] encoding of result to escaped HTML, compatible with any browser. |
escape |
Turn on [default]/off escaping of HTML tags in text nodes (prevents XSS attacks in case you pass untrusted data to json2html). |
pip install json2html
Or, Download here and run python setup.py install
after changing directory to /json2html
Example 1: Basic usage
from json2html import *
input = {
"name": "json2html",
"description": "Converts JSON to HTML tabular representation"
}
json2html.convert(json = input)
Output:
<table border="1"><tr><th>name</th><td>json2html</td></tr><tr><th>description</th><td>converts JSON to HTML tabular representation</td></tr></table>
name | description |
---|---|
json2html | Converts JSON to HTML tabular representation |
Example 2: Setting custom attributes to table
from json2html import *
input = {
"name": "json2html",
"description": "Converts JSON to HTML tabular representation"
}
json2html.convert(json = input, table_attributes="id=\"info-table\" class=\"table table-bordered table-hover\"")
Output:
<table id="info-table" class="table table-bordered table-hover"><tr><th>name</th><td>json2html</td></tr><tr><th>description</th><td>Converts JSON to HTML tabular representation</td></tr></table>
Example 3: Clubbing same keys of: Array of Objects
from json2html import *
input = {
"sample": [{
"a":1, "b":2, "c":3
}, {
"a":5, "b":6, "c":7
}]
}
json2html.convert(json = input)
Output:
<table border="1"><tr><th>sample</th><td><table border="1"><thead><tr><th>b</th><th>c</th><th>a</th></tr></thead><tbody><tr><td>2</td><td>3</td><td>1</td></tr><tr><td>6</td><td>7</td><td>5</td></tr></tbody></table></td></tr></table>
a | c | b |
---|---|---|
1 | 3 | 2 |
5 | 7 | 6 |
Example 4: Each row for different key(s) of: Array of Objects
from json2html import *
input = {
"sample": [{
"a":1, "b":2, "c":3
}, {
"1a1":5, "1b1":6, "c":7
}]
}
json2html.convert(json = input)
Output:
<table border="1"><tr><th>sample</th><td><ul><li><table border="1"><tr><th>a</th><td>1</td></tr><tr><th>c</th><td>3</td></tr><tr><th>b</th><td>2</td></tr></table></li><li><table border="1"><tr><th>1b1</th><td>6</td></tr><tr><th>c</th><td>7</td></tr><tr><th>1a1</th><td>5</td></tr></table></li></ul></td></tr></table>

from json2html import *
input = {
"glossary": {
"title": "example glossary",
"GlossDiv": {
"title": "S",
"GlossList": {
"GlossEntry": {
"ID": "SGML",
"SortAs": "SGML",
"GlossTerm": "Standard Generalized Markup Language",
"Acronym": "SGML",
"Abbrev": "ISO 8879:1986",
"GlossDef": {
"para": "A meta-markup language, used to create markup languages such as DocBook.",
"GlossSeeAlso": ["GML", "XML"]
},
"GlossSee": "markup"
}
}
}
}
}
json2html.convert(json = input)
Output:
<table border="1"><tr><th>glossary</th><td><table border="1"><tr><th>GlossDiv</th><td><table border="1"><tr><th>GlossList</th><td><table border="1"><tr><th>GlossEntry</th><td><table border="1"><tr><th>GlossDef</th><td><table border="1"><tr><th>GlossSeeAlso</th><td><ul><li>GML</li><li>XML</li></ul></td></tr><tr><th>para</th><td>A meta-markup language, used to create markup languages such as DocBook.</td></tr></table></td></tr><tr><th>GlossSee</th><td>markup</td></tr><tr><th>Acronym</th><td>SGML</td></tr><tr><th>GlossTerm</th><td>Standard Generalized Markup Language</td></tr><tr><th>Abbrev</th><td>ISO 8879:1986</td></tr><tr><th>SortAs</th><td>SGML</td></tr><tr><th>ID</th><td>SGML</td></tr></table></td></tr></table></td></tr><tr><th>title</th><td>S</td></tr></table></td></tr><tr><th>title</th><td>example glossary</td></tr></table></td></tr></table>
cd test/
python run_tests.py
Tested on Python 2.7 and 3.5+.
-
Michel Mueller: @muellermichel
- Added support for clubbing Array of Objects with same keys, more readable format.
- Added support for adding custom
table_attributes
. - Convert now accepts unicode and bytestrings for the keyword argument "json".
- Output now should always appear in the same order as input.
- Now supports JSON Lists (at top level), including clubbing.
- Now supports empty inputs and positional arguments for convert.
- Python 3 support ; Added integration tests for Python 2.6, 3.4 and 3.5 such that support doesn't break.
- Can now also do the proper encoding for you (disabled by default to not break backwards compatibility).
- Can now handle non-JSON objects on a best-effort principle.
- Now by default escapes html in text nodes to prevent XSS attacks.
-
Daniel Lekic: @lekic
- Fixed issue with one-item lists not rendering correctly.
- General code cleanup, fixed all naming conventions and coding standards to adhere to PEP8 conventions.
-
Kyle Smith: @smithk86
- Added thead and tbody tags to group header and content rows when creating a table from an array of objects.
