If not, // then default to comma. strDelimiter = (strDelimiter || ","); // Create a regular expression to parse the CSV values. var objPattern = new RegExp( ( // Delimiters.

    1. COThis can handle embedded commas, quotes and line breaks, eg.: var csv = 'id, value\n1, James\n02,"Jimmy Smith, Esq."\n003,"James ""Jimmy"" Smith, III"\n0004,"James\nSmith\nWuz Here"' var array = CSVToArray(csv, ",");

    2. COThis has worked for a wide variety of files. I find that it appends an extra blank row at the end. Not sure if this is the best way to but suggest adding a check that the new line has at least one value, even if explicitly blank "" ` if (arrMatches[2] || arrMatches[3]) { arrData.push([]); rowCount++; } else { break; } }`

    3. COIt gives `undefined` for __empty fields__ that is __quoted__. Example: `CSVToArray("4,,6")` gives me `[["4","","6"]]`, but `CSVToArray("4,\"\",6")` gives me `[["4",undefined,"6"]]`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
