- Working
CSV to XLSX
Open a CSV in a spreadsheet using a one-sheet XLSX workbook. Every field is a literal text cell.
Data Converters - Working
XLSX to CSV
Choose a worksheet from an XLSX workbook and export its cells as comma-separated values.
Data Converters - Working
JSON to CSV
Build a table from the top-level keys in a JSON array of objects. Nested values stay in one cell as compact JSON.
Data Converters - Working
CSV to JSON
Use the CSV header row as JSON object keys. Preserve leading zeros, Unicode and quoted contents as text values.
Data Converters - Working
CSV to TSV
Change the delimiter from comma to tab while parsing quoted records and fields.
Data Converters - Working
TSV to CSV
Read tab-separated records and write valid CSV with the quoting each field needs.
Data Converters - Working
JSON Formatter
Make JSON easier to read while retaining the original spelling of numbers, strings and object keys.
Data Converters - Working
JSON Validator
Check whether your JSON parses and get an error message when the syntax is invalid.
Data Converters - Working
JSON to XLSX
Build a spreadsheet from a JSON array of objects. Top-level keys become columns, and nested structures stay together in a cell.
Data Converters - Working
XLSX to JSON
Export a workbook sheet as JSON objects with column names or as arrays that retain every cell position.
Data Converters - Working
TSV to XLSX
Turn a tab-delimited table into a one-sheet workbook while keeping quoted tabs and newlines inside their cells.
Data Converters - Working
XLSX to TSV
Export one workbook sheet as tab-separated text for tools that can read quoted TSV fields and empty cells.

Move tables into a workbook
CSV, TSV and tabular JSON become one XLSX worksheet with literal text cells. This keeps leading zeros and prevents formula-like values from becoming formulas. Numeric-looking fields stay text.
Export one worksheet
Choose a sheet and export its stored values. Formula results come from saved caches. Date serials remain numeric strings, and styles are omitted. CSV and TSV exports disclose apostrophes added to formula-like fields.
Work with JSON records
CSV headers become JSON keys with string values. JSON to CSV keeps nested arrays and objects as compact JSON in a cell. The formatter retains numeric tokens, while the validator checks syntax within its depth limit.
