Posted on by IM-18071459-0

Hello,

i am using Microsoft Dynamics NAV 2017 version.

I am sending data through JSON.

Variable: JsonTextWriter

Datatype: DotNet

Subtype: Newtonsoft.Json.JsonTextWriter.'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'

JsonTextWriter.WriteValue(TextField1 + '\n' + TextField2 + '\n'+ TextField3);

The output comes in one single line, but i want it to be break and go on another line after each TextField

TextField1

TextField2

TextField3

any suggestions?

Hi,

When using JsonTextWriter.WriteValue() from Newtonsoft.Json in Dynamics NAV 2017, the method escapes newline characters (\n) and writes the entire value as a single JSON string. This is expected behavior, as JSON strings do not interpret \n as actual line breaks when rendered—they remain as literal escape sequences.

To achieve line breaks in the output, you have a couple of options:

Use WriteRaw() Instead of WriteValue()
If you're constructing a JSON object manually and want to insert raw line breaks, you can use:

JsonTextWriter.WriteRaw('"' + TextField1 + '\n' + TextField2 + '\n' + TextField3 + '"');

This writes the string exactly as you format it, including the escape sequences.

Use Environment.NewLine (if supported)
If you're writing to a file or stream and want actual line breaks (not escaped \n), you can build the string using

CombinedText := TextField1 + Environment.NewLine + TextField2 + Environment.NewLine + TextField3;

JsonTextWriter.WriteValue(CombinedText);

However, this still results in a single JSON string with escaped newlines unless the consumer of the JSON interprets them.

Post-process the output
If the JSON is being consumed by a system that renders text (e.g., a UI or report), ensure that the consumer interprets \n as line breaks. If not, you may need to split the values into an array:

JsonTextWriter.WriteStartArray();

JsonTextWriter.WriteValue(TextField1);

JsonTextWriter.WriteValue(TextField2);

JsonTextWriter.WriteValue(TextField3);J

sonTextWriter.WriteEndArray();

This way, each value is a separate element, and the consumer can render them on separate lines.

Please verify if this response was helpful.

Best regards,
Daniele

To ensure that each TextField appears on a new line in your JSON output, you can use the escape sequence for a newline character (\r\n or \n). Modify your code as follows: [url=https://headbasketball.io][color=#FFFFFF]head basketball game[/color][/url]

Copy

JsonTextWriter.WriteValue(TextField1 + '\r\n' + TextField2 + '\r\n' + TextField3);

This will create the desired line breaks in the output.

If you’re using JsonTextWriter.WriteValue() with something like TextField1 + '\n' + TextField2, those \n get escaped in JSON and show up as \\n — that’s actually correct per the JSON spec.

If you just want to see the actual line breaks, you’ll need to unescape the JSON string after serialization. I often use a Unescape JSON tool. Paste your JSON there, and it instantly converts \n into real newlines.

And if you need the reverse — taking text and escaping it for JSON — another Escape JSON tool helps too. Both run fully in-browser and are great for quick debugging.
