wrong sorting of numeric keys!
Excellent extensions. I tried JSONFormatter and JSONView. I chose the JSONView. The JSONFormatter has the following features that are not in JSONView: (a) [Show Original] button [NOT TRUE anymore. JSONView can view source now. But once you view source you can't switch back to json view ] , (b) When collapsed, there's a remark like "// 3items" right next to the collapsible header to tell you how many items are inside the collapsed. This would be very useful if you have complicated json data. I chose the JSONView for the following reasons: (1) If your json data contains html string, JSONView prettified it, too. But with JSONFormatter, you see a whole junk of text packed together; (2) With JSONView you can customized the style. I added a line "border:1px lightgray dotted" to the #collapsible, so all collapsible blocks have a light color border. I can't do that with JSONFormatter. Both are good but the features of JSONView are more critical to me. [update Sep.7.12] Two issues with JSONView: 1. JSONView seems to keep a copy of your json file in the browser window. If your json file is modified, JSONView keeps loading the old copy even you ask the browser to refresh. The only way to view the modified json is to close the window or tab (not the browser) and restart a new window for the new json; 2. Even though it is collapsible, it won't collapse a long string. If your json contains a long html doc as value, it fails to collapse it.
Handy
Muito bom, era exatamente o que estava buscando em um visualizador para JSON
Very useful! Good work Gildas!
Good~
It's not optimized for huge JSON files but it does an awsome job on regular JSON responses.
double post. maybe bug,please fix
Works really well. However I wish I could use it as an editor as well. I tried using copy and paste with Notepad++ and carried the line returns, but I wish it would have the tabs in place. Overall Goodwork!
This is super useful, thank you!
