+operator string_t() const
+```
+
+Return a string representation of the JSON pointer.
+
+## Return value
+

+
+## Possible implementation

+operator string_t() const
+{

+}
+```
+
+## Notes
+
+Deprecation
+
+This function is deprecated in favor of [`to_string`](https://json.nlohmann.me/api/json_pointer/to_string/index.md) and will be removed in a future major version release.
+
+## Examples
+
+Example
+
+The example shows how JSON Pointers can be implicitly converted to strings.
+
+```
+#include <iostream>
+#include <nlohmann/json.hpp>
+
+using json = nlohmann::json;
+
+int main()
+{
+    // different JSON Pointers
+    json::json_pointer ptr1("/foo/0");
+    json::json_pointer ptr2("/a~1b");
+
+    // implicit conversion to string
+    std::string s;
+    s += ptr1;
+    s += "\n";
+    s += ptr2;
+
+    std::cout << s << std::endl;
+}
+```
+
+Output:
+
+```
+/foo/0
+/a~1b
+```
