Free online X82 to XML converter

Applications that accept structured XML may require an X82 export to be converted before the data can be imported, edited, or archived. The correct procedure depends on the program that created the file because .x82 is not a single standardized Internet data format.

What the X82 format is

.x82 is an application-specific extension rather than a universally defined Internet format with one official reader or schema. An X82 file may contain structured records, configuration data, or an export generated by a particular web, catalog, or data-processing application; the filename alone does not identify its fields or encoding.

Find the creating program in the download source, file properties, documentation, or the first bytes of the file. A plain-text X82 file may begin with readable tags, delimiters, or a header; a binary header indicates that a direct text conversion is unlikely to preserve its data.

What the XML format is

XML stores hierarchical data as elements and attributes encoded in plain text. It is useful for exchanging records between applications, validating data against an XSD schema, processing content with XPath or XSLT, and preserving structured information in archives.

XML does not automatically define the meaning of an X82 field. A useful result requires a mapping from the source fields to XML element names, attributes, data types, namespaces, and character encoding. The receiving application may also require a specific XML schema.

How to actually convert X82 to XML

1. Make a backup of the original .x82 file and identify the application that created it.
2. Check that application for an export command such as File → Export → XML, Save as → XML, or an API export option. This is preferable because the source program knows the X82 field definitions.
3. If the file is supported by the built-in converter, open 101convert.com, choose the X82-to-XML conversion, upload the file, and download the generated .xml file. The online conversion is free and requires no software installation.
4. Open the result in a text editor and verify that it is well-formed XML: it should have one root element, properly nested tags, quoted attribute values, and valid character encoding.
5. Validate the file against the schema required by the destination system. With a local XML tool, a basic syntax check can be performed with xmllint --noout output.xml; this checks well-formedness, not whether the data matches the target application's schema.

If the converter cannot recognize the X82 file, export it from the original application or obtain its field specification. A custom script can then parse the source records and write XML, but it must explicitly handle delimiters, dates, numeric formats, escaped characters, duplicate records, and missing values.

Compatibility and limitations

Changing the filename extension from .x82 to .xml does not convert the data. Generic text conversion can also produce XML that is syntactically valid but semantically unusable if the source structure is undocumented.

Check non-ASCII characters, line endings, namespaces, timestamps, decimal separators, and embedded binary or linked files after conversion. Compare record counts and representative field values with the original, then test the XML in the target application; unsupported X82 features may be omitted or flattened.
