Comparison with existing tool

Testing with a 1mb json file, containing only 1000 rows and 220 different fields

Json crack

It fails to render anything with a 1mb json file, containing only 1000 rows and 220 different fields. On firefox the tab crash

json2table/jsontableviewer

It takes time to render the table, then it is almost impossible to read anything when there are lot of data due to the layout used: nested fields are rendered as sub-table generating extra space in each rows

jsongrid

It tries to not render all rows at once but it generate lag when scrolling. In addition only 100 rows can be displayed at once, making the experience not smooth

Jsonmatrix
