Data File Check

DATA FILE CHECK

Check a data file

Inspect JSON, XML, and CSV syntax, structure, delimiters, encoding, row consistency, and extension mismatches directly in your browser.

WHEN TO USE THIS CHECK

Data file won’t parse, import, or open correctly?

Start with the file itself. ARADURU checks whether supported structured-data files can be parsed consistently before you assume the destination application is the problem.

JSON syntax looks invalid Check whether the complete JSON document parses and whether its root structure is readable.
XML is malformed or incomplete Check well-formedness, the root element, and the parsed XML element structure.
CSV rows do not line up Check delimiter detection, quoted fields, row count, column count, and inconsistent rows.
The filename extension may be wrong Compare strong JSON or XML content evidence with the filename and preserve the original before renaming.

WHAT ARADURU CHECKS

Structure checks for JSON, XML, and CSV

Each format uses a different parser. ARADURU reports file-side evidence without pretending to validate every application schema or business rule.

JSON

JSON syntax and nesting

UTF-8 decoding, complete JSON parsing, root type, top-level item or key count, and parsed nesting depth.

XML

XML well-formedness

UTF-8 decoding, browser XML parsing, root element, element count, and element nesting depth.

CSV

Delimited table structure

Balanced quoted fields, comma/tab/semicolon/pipe detection, row count, column count, and inconsistent-row warnings.

WHAT THIS DOES NOT GUARANTEE

Readable structure is not the same as valid business data.

A JSON, XML, or CSV file can parse successfully and still fail a destination’s schema, required-field, type, encoding-policy, import, or business-rule requirements.

  1. Keep the original. Test edits, renames, or repairs on a copy.
  2. Check the destination rules. A valid file can still violate an API or import schema.
  3. Use Compatibility Check. Review the file-side structure separately from application support.
  4. Use Upload Check. Compare file type, size, and filename rules before submission.
