JSON Importer for Survey

Load answer sets into a Survey form from JSON. Use this when another system already produces JSON — API responses, webhook payloads, exported files — or when you want the cleanest programmatic integration path.

Features

• Bidirectional — same Form schema used for serializing a designed survey is used to parse answers into typed ElementValue objects
• Handles the full element set — strings, ints, lists of typed returns (CheckboxReturn, DropdownListReturn, ImagePickerReturn, MatrixReturn, RadiobuttonReturn), matrix coordinates, slider values
• Validation against the form schema — unknown keys flagged, required fields checked, type mismatches surfaced with the offending path
• Polymorphic-aware — uses the same ElementTypeConverter the runtime uses, so any valid runtime JSON is importable
• Typed JsonImportResult — success / failed counts, per-record errors, parsed values ready to bind

What's included

• Compiled NuGet package (PSC.Survey.Shared.Imports.Json) targeting netstandard2.1
• Full README with examples for every element type's JSON shape
• LICENCE.md (one developer, annual commercial licence, unlimited end users, no redistribution)

Add to your project

dotnet add package PSC.Survey.Shared.Imports.Json

using PSC.Survey.Shared.Imports.Json;

var importer = new JsonImport();
var result = importer.ImportData(jsonText, form);

foreach (var record in result.Records)
    if (record.Success)
        Save(record.Values);

Requirements

• .NET 6 / 8 / 10 (netstandard2.1)
• PSC.Survey.Shared (models) — included as a NuGet dependency

Pair with

• Survey runtime — render the form and submit answers as JSON
• CSV / Excel importers — same API for tabular formats
