XML to CSV frequently asked questions

Upload the XML file, create a preview, and review the detected tables, columns, relationships, row counts, and CSV file names. When the preview looks correct, select Convert and download ZIP.

Tidelose detects repeating table-like elements in the XML. Nested structures can become separate CSV files instead of being forced into one wide table. The preview shows the proposed structure before any CSV files are generated.

Yes. Where related tables are detected, generated _row_id and _parent_row_id columns link child rows back to their parent rows. See the structured versus flattened conversion guide for an example.

Attributes and child values can be detected as candidate columns. Review the detected columns in the preview to confirm how your particular XML structure will be exported.

Yes. Each detected table can become its own CSV file. Tidelose packages the related CSV files together in one ZIP archive and lets you review or rename their file names before conversion.

The converter reports validation issues instead of silently producing unreliable output. For supported problems, it can offer a preview retry after removing a DTD declaration or escaping bare ampersands.

The current maximum upload size is 25 MB, and a conversion has a 30-second processing timeout. The converter displays the active limits beside the file picker. We are developing a large-file version designed to process XML files in the 1–2 GB range; availability and final limits will be confirmed when that version is ready.

Active previews and generated ZIP files expire after 2 hours. Failed or invalid conversions expire after 24 hours, after which automated cleanup removes their files and records.

Yes. Extract the downloaded ZIP archive, then open or import the individual CSV files in Excel or another spreadsheet, database, or data-analysis tool.
