 The app primarily wraps one function: `ds2dd_detailed()`.
 
 ```{r}
-REDCap_split(
+library(REDCapCAST)
+ds <- REDCap_split(

     metadata = redcapcast_meta,
     forms = "all"

+str(ds)
 ```
 
+```{r}

+  purrr::pluck("data") |> 
+  str()

+```{r}
+ds|> 
+  ds2dd_detailed()|>  
+  purrr::pluck("meta") |> 
+  head(10)
+```
+
+Different data formats are accepted, which all mostly implements the `readr::col_guess()` functionality to parse column classes.
+
+To ensure uniformity in data import this parsing has been implemented on its own to use with `ds2dd_detailed()` or any other data set for that matter:
+
+```{r}
+ds_parsed <- redcapcast_data |> 
+  dplyr::mutate(dplyr::across(dplyr::everything(),as.character)) |> 
+  parse_data()
+str(ds_parsed)
+```
+
+It will ignore specified columns, which is neat for numeric-looking strings like cpr-with a leading 0:
 
 ```{r}
 redcapcast_data |> 
   dplyr::mutate(dplyr::across(dplyr::everything(),as.character)) |> 
-  readr::type_convert( 
-      col_types = readr::cols(.default = readr::col_guess()))
+  parse_data(ignore.vars = c("record_id","cpr")) |> 
+  str()
 ```
 
 
+```{r}
+
+```
+
+
+Column classes can be passed to `parse_data()`.
+
+Making a few crude assumption for factorising data, `numchar2fct()` factorises numerical and character vectors based on a set threshold for unique values:
+
+```{r}
+mtcars |> str()
+mtcars |>
+  numchar2fct(numeric.threshold = 6) |>
+  str()
+```
+
+```{r}
+ds_parsed|>
+  numchar2fct(numeric.threshold = 2) |>
+  str()
+```
