Handle self-closing XML tags (no upload)

What this problem looks like

XML failures are usually escaping/namespace/structure mismatches that break parser expectations.

Treat errors as signals. Fix the input format first, validate locally, then convert and export.

• Validate first: run a local validator for strict JSON/XML/CSV.
• Sample: test 20–50 rows/items before processing a full export.
• Spot-check: verify a few keys/rows before downloading.

Practical checklist (fast)

Use a fast checklist: confirm strict syntax, confirm expected shape, and only then convert. This reduces “random fixing” and prevents exporting broken output.

If you handle sensitive data, local processing avoids accidental uploads while debugging.

• Confirm your delimiter/quotes for CSV or your tag structure for XML.
• Confirm JSON is strict (double quotes, no trailing commas, no comments).
• Export only after the sample output looks correct.

Local conversion workflow

For CSV and JSON exports, keep transformations simple: parse → normalize → serialize. When issues appear, fix the input rather than adding hidden “auto-fixes”.

Use the built-in download/copy actions to move data to the next step without sending it to a server.

With self-closing tags (for example <phone />), decide how you want “empty” represented in JSON. Different downstream systems treat empty strings and nulls differently.

• Empty element: map to "" if “present but empty” matters.
• Missing element: omit the key if “not provided” is meaningful.
• Explicit null: map to null if you want to keep a stable key but signal emptiness.

Trust note: All processing happens locally in your browser. Files are never uploaded.

FAQ

Why does it work in one tool but not in another? Different tools accept different non-standard inputs. Stick to strict JSON/XML/CSV for reliability.

Is it safe to convert private files online? If privacy matters, prefer local no-upload tools and verify via the Network tab.

const doc = new DOMParser().parseFromString(xmlText, 'application/xml');
const err = doc.querySelector('parsererror');
if (err) throw new Error(err.textContent || 'Invalid XML');
console.log('XML is well-formed');
