Data tools

Choose the right data tool

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.
