A little guidance before you convert
Select a worksheet by name or export all sheets as a ZIP for CSV/JSON. CSV stores values only. Text stays text to preserve identifiers and leading zeros; cached formula values are exported, and missing cached results are reported. Formula-like text is protected by default. Text inputs: up to 10 MB; tables: 50,000 rows, 200 columns and 200,000 cells in total.
