CORS Header Generator
Generate correct CORS headers, and understand why the request was blocked.
Convert CSV rows into XML records with named root and row elements.
The CSV to XML converter writes each row as a record element inside a named root, with columns as child elements or attributes, header names made valid as element names, and reserved characters escaped.
Plenty of systems still want XML: older APIs, financial and healthcare interchange formats, product feeds and government uploads. Converting a spreadsheet export into one by hand is tedious and easy to get subtly wrong.
Each CSV row becomes a record element inside a named root, and each column becomes either a child element or an attribute — some schemas want one, some the other. Column headers are made safe as element names: spaces and punctuation become underscores, and a name starting with a digit gets a prefix, because XML forbids that. Ampersands and angle brackets in the data are escaped properly, which is the single most common cause of a rejected upload.
Set the root and the per-row element, so the output matches whatever schema is expecting it.
Columns can become child elements or attributes on the row element, because schemas disagree about which they want.
Spaces and punctuation become underscores and a leading digit gets a prefix, since XML element names allow neither.
An unescaped ampersand is the classic cause of a rejected XML upload, so text and attribute values are both escaped properly.
Version 1.0 and UTF-8 on the first line, which is what most validators and importers expect to see.
Include the header row — it names the elements or attributes.
Set the root element and the element used for each row.
Columns can become child elements or attributes on the row element.
Take the XML to your clipboard or save it as an .xml file.
Spaces and punctuation become underscores, since XML element names cannot contain them. A header starting with a digit gets an underscore prefix for the same reason.
Yes. Ampersands, less-than and greater-than are converted to entities in text, and quotes are escaped in attribute values. An unescaped ampersand is the classic cause of a rejected XML upload.
Whatever the receiving schema specifies. As a rule of thumb, attributes suit short identifiers and metadata, and elements suit content and anything that might later need children.
Yes, with version 1.0 and UTF-8 encoding, which is what most validators and importers expect on the first line.
