                            The formatter runs entirely in the browser, so no data is sent to the server.

Quick answers for the JSON Formatter.

                

                

                    

                        

                            

                                
                            

                        

                        

                            

                                Yes. The formatting logic is client-side, so the data never leaves the browser.                            

                        

                    

                    

                        

                            

                                
                            

                        

                        

                            

                                Yes. Invalid JSON is highlighted with a clear error message before formatting or minifying.                            

                        

                    

                    

                        

                            

                                
                            

                        

                        

                            

                                Yes. The route map keeps room for a future API Center, but the first release stays simple and free.
