TO_JSON

TO_JSON

A lightweight Pine Script v6 library for converting TradingView series data into JSON-formatted alert payloads.

`TO_JSON` is designed for users who want to export chart data to external systems through TradingView alerts.
It helps transform rolling series such as OHLCV, indicator values, or text states into JSON-compatible arrays and wraps them into a structured message for webhooks, bots, dashboards, or automated workflows.

What this library does

This library provides helper functions to:

- convert float series into JSON arrays
- convert integer series into JSON arrays using a sentinel value as `null`
- convert string series into JSON arrays with fallback filling and JSON-safe escaping
- wrap custom payloads into a top-level JSON alert message with symbol, timeframe, timestamp, and token

It is especially useful when you want to send the latest `N` bars of market data or indicator values to an external service.

Features

- Rolling array export for `float`, `int`, and `string` series
- Chronological output from oldest to newest
- `null` support for missing values
- JSON-safe string escaping
- Simple wrapper for alert message generation
- Works well for webhook-based automation and downstream parsing

Exported functions

### `series_to_array_float_null(series float src, int N)`

Converts the latest `N` values of a float series into a JSON array string.
Missing values are exported as `null`.

`series_to_array_int_sentinel(series int src, int N, int sentinel)`

Converts the latest `N` values of an integer series into a JSON array string.
The specified sentinel value is exported as `null`.

`series_to_array_str_fill(series string src, int N, string fill="")`

Converts the latest `N` values of a string series into a JSON array string.
Missing values are replaced with `fill`, and strings are escaped for JSON compatibility.

`json(simple string token="1234567890", string info="", simple string symbol="AUTO")`

Wraps a custom JSON payload into a top-level alert message including:

- symbol
- timeframe
- current timestamp
- human-readable time
- info payload
- token

Typical use case

A common use case is exporting the last bars of:

- time
- open
- high
- low
- close
- volume
- moving averages
- custom signals

into one flat JSON object, then embedding it into the alert message.

Example

```pine
//version=6
import veegee82/TO_JSON/1 as json

indicator("TO_JSON Example", overlay=false)

stO = open
stH = high
stL = low
stC = close
stV = volume

ema_50 = ta.ema(close, 50)
ema_100 = ta.ema(close, 100)
ema_200 = ta.ema(close, 200)
ema_500 = ta.ema(close, 500)
ema_1000 = ta.ema(close, 1000)

json_flat(int n=50) =>
s_name = '"name":"' + 'vision_' + timeframe.period + '"'
s_tf = ',"timeframe":"' + timeframe.period + '"'
s_ts = ',"ts":' + json.series_to_array_float_null(time, n)

s_o = ',"open":' + json.series_to_array_float_null(stO, n)
s_h = ',"high":' + json.series_to_array_float_null(stH, n)
s_l = ',"low":' + json.series_to_array_float_null(stL, n)
s_c = ',"close":' + json.series_to_array_float_null(stC, n)
s_v = ',"volume":' + json.series_to_array_float_null(stV, n)

s_ema_50 = ',"ema_50":' + json.series_to_array_float_null(ema_50, n)
s_ema_100 = ',"ema_100":' + json.series_to_array_float_null(ema_100, n)
s_ema_200 = ',"ema_200":' + json.series_to_array_float_null(ema_200, n)
s_ema_500 = ',"ema_500":' + json.series_to_array_float_null(ema_500, n)
s_ema_1000 = ',"ema_1000":' + json.series_to_array_float_null(ema_1000, n)

"{" + s_name + s_tf + s_ts + s_o + s_h + s_l + s_c + s_v + s_ema_50 + s_ema_100 + s_ema_200 + s_ema_500 + s_ema_1000 + "}"

info = json_flat(100)

alert(
message = json.json(token = "1234567890", info = info, symbol = "AUTO"),
freq = alert.freq_once_per_bar_close
)
