Generate list from JavaScript object

This is my data:

var tabledata = {
0: {Name: "Server1", PRPName: "NO_PRP", OperatingSystem: "Linux", SLA: "SILVER", Environment: "Accept"}
1: {Name: "Server2", PRPName: "services", OperatingSystem: "Linux", SLA: "SILVER", Environment:"Accept"}
2: {Name: "Server3", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"}
3: {Name: "Server4", PRPName: "services", OperatingSystem: "Linux", SLA: "GOLD", Environment: "Accept"}
4: {Name: "Server5", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"}
5: {Name: "Server6", PRPName: "sql", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"}
6: {Name: "Server7", PRPName: "services", OperatingSystem: "Linux", SLA: "GOLD", Environment: "Production"}
7: {Name: "Server8", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Production"}
8: {Name: "Server9", PRPName: "sql", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Production"}

And i need to create a list from Name: like this.

servernames = ["Server1","Server2","Server3","Server4","Server5","Server6","Server7","Server8"]

As pointed out by the others, you have a JavaScript object (a map between numbers and objects representing server data), and not a JSON.

To get the server names from this object, you can use Object.values to first extract the object's property values with server information and then map to get only the server name, generating an array with those:

var tabledata = {
  0: {Name: "Server1", PRPName: "NO_PRP", OperatingSystem: "Linux", SLA: "SILVER", Environment: "Accept"},
  1: {Name: "Server2", PRPName: "services", OperatingSystem: "Linux", SLA: "SILVER", Environment:"Accept"},
  2: {Name: "Server3", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"},
  3: {Name: "Server4", PRPName: "services", OperatingSystem: "Linux", SLA: "GOLD", Environment: "Accept"},
  4: {Name: "Server5", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"},
  5: {Name: "Server6", PRPName: "sql", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"},
  6: {Name: "Server7", PRPName: "services", OperatingSystem: "Linux", SLA: "GOLD", Environment: "Production"},
  7: {Name: "Server8", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Production"},
  8: {Name: "Server9", PRPName: "sql", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Production"}
};
var servernames = Object.values(tabledata).map((server) => server.Name);

console.log(servernames);

Your JSON:

var tabledata = {
"0": {Name: "Server1", PRPName: "NO_PRP", OperatingSystem: "Linux", SLA: "SILVER", Environment: "Accept"},
"1": {Name: "Server2", PRPName: "services", OperatingSystem: "Linux", SLA: "SILVER", Environment:"Accept"},
"2": {Name: "Server3", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"},
"3": {Name: "Server4", PRPName: "services", OperatingSystem: "Linux", SLA: "GOLD", Environment: "Accept"},
"4": {Name: "Server5", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"},
"5": {Name: "Server6", PRPName: "sql", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"},
"6": {Name: "Server7", PRPName: "services", OperatingSystem: "Linux", SLA: "GOLD", Environment: "Production"},
"7": {Name: "Server8", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Production"},
"8": {Name: "Server9", PRPName: "sql", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Production"}
};

You could use Object.values to get an array of values of your tabledata object and then apply Array.prototype.map to transform the values to server names like so:

const serverNames = Object.values(tabledata).map((server) => server.Name);
console.log(serverNames);

It will print:

["Server1", "Server2", "Server3", "Server4", "Server5", "Server6", "Server7", "Server8", "Server9"]

Try this one:

var tabledata = {
0: {Name: "Server1", PRPName: "NO_PRP", OperatingSystem: "Linux", SLA: "SILVER", Environment: "Accept"},
1: {Name: "Server2", PRPName: "services", OperatingSystem: "Linux", SLA: "SILVER", Environment:"Accept"},
2: {Name: "Server3", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"},
3: {Name: "Server4", PRPName: "services", OperatingSystem: "Linux", SLA: "GOLD", Environment: "Accept"},
4: {Name: "Server5", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"},
5: {Name: "Server6", PRPName: "sql", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Accept"},
6: {Name: "Server7", PRPName: "services", OperatingSystem: "Linux", SLA: "GOLD", Environment: "Production"},
7: {Name: "Server8", PRPName: "NO_PRP", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Production"},
8: {Name: "Server9", PRPName: "sql", OperatingSystem: "Windows", SLA: "GOLD", Environment: "Production"}
}

const result = Object.keys(tabledata).map(el => tabledata[el].Name)
console.log(result)
