How it works

Choose files, check the detected format and select an available conversion. Adjust options, convert, then download. Reset to release results.

Data

UTF-8 only. CSV headers must be unique; without headers, JSON uses arrays of rows. JSON to CSV accepts flat objects or rectangular arrays only: null becomes an empty cell and CSV has no type information. Spreadsheet-sensitive CSV/TSV values receive a leading apostrophe. TXT to CSV requires at least two consistent columns.

XML to JSON preserves names, attributes (strings), and ordered children (text or element objects); comments are omitted. JSON to XML uses typed null/boolean/number/string/array/object tags under xunglee-json, with object keys in entry attributes. These two mappings are different. YAML uses the JSON schema, no aliases, custom tags or non-JSON types. Maximum depth: 40; values/cells: 100,000. JSON numbers use JavaScript precision.

How to use it

Select the actual source and destination formats. An extension rename is not conversion. Try a representative file first and review the format-specific limitations before converting a whole batch.

Worked example

A CSV is a table of text values, while XLSX can contain formulas, worksheets and formatting. Moving between them cannot preserve every workbook feature. A DOCX-to-text conversion extracts content rather than reproducing a Word page layout.

Interpretation and limits

Open the downloaded result in its intended application and compare headings, accents, rows and numbers. Keep the original. A successful conversion does not guarantee lossless formatting or neutralize malicious content for every downstream application. Only supported format pairs are offered.
