Keep single-line records, change the separator
Handles quoted delimiters within a physical line, but not multiline fields. Replacing every comma with a tab corrupts quoted data; multiline CSV needs a full parser.

Choose a conversion by the data you must preserve
Before changing file syntax, identify identifiers, nested values, empty fields and line breaks. A parseable output can still change the meaning of a record.
Move flat records between JSON and a table
Decide the columns and types before conversion. Nested objects and missing fields need an explicit mapping.
Inspect XML as JSON data
Check how attributes, repeated elements and mixed text are represented. XML and JSON do not have the same data model.
Preserve an identifier and a quoted comma
CSV input: id,note 00123,"hello, world" Expected TSV fields: id note 00123 hello, world
The record has two fields. Keep 00123 as text in the destination application and preserve the comma inside note. Compare parsed values and row counts instead of only checking the new extension.
A filename change is not a format conversion. Spreadsheet auto-typing and formula interpretation happen in the receiving application and need a separate import check.
