How can I create something more complex Json Data
with json from tcllib and process it in tcl. How does this work with json from tcllib?

Or do I have to use rl_json or tjson?

Example:

package require json
#https://core.tcl-lang.org/tcllib/doc/trunk/embedded/md/tcllib/files/modules/json/json.md
set jsonData {
"simple": {
"greeting": "Hello, World!",
"number": 123,
"boolean": false,
"nullValue": null
},
"array": [
"apple",
"banana",
"cherry"
],
"nested": {
"level1": {
"level2": {
"level3": "deep value"
}
}
}
}

set tclData1 [catch {::json::json2dict $jsonData} err1 ]
set tclData2 [catch {::json::json2dict {*}$jsonData} err2 ]
set tclData3 [catch {::json::many-json2dict $jsonData} err3 ]
set tclData4 [catch {::json::many-json2dict {*}$jsonData} err4 ]

puts "1: $tclData1 e: $err1"
puts "2: $tclData1 e: $err2"
puts "3: $tclData1 e: $err3"
puts "4: $tclData1 e: $err4"

if {0} {
Output:
1: 0 e: simple
2: 0 e: list element in quotes followed by ":" instead of space
3: 0 e: unexpected token ":" at position 2; expecting VALUE
4: 0 e: list element in quotes followed by ":" instead of space
}

I think it is not a valid JSON document. Try enclosing it in an extra
pair of { and } where you say "set jsonData ..."

Thank you, that's it.
