Examples
With target 0 to 1, source values 0, 1, 3 become 0, 0.333333, 1 at six fractional places.
Limitations
- At most 1 MiB UTF-8, 10000 data rows, 100 columns and 100000 cells including headers; 20 MiB combined output and 30 seconds.
- Selected numeric inputs and endpoints admit an optional sign, at most 18 digits total and six fractional digits, with no exponent or spaces. Precision 0–12 uses exact half-away-from-zero rounding. Constant and empty columns follow explicit policies.
- Existing spreadsheet formula protection is on by default; formula-sensitive output strings can gain an apostrophe. CSV cannot declare spreadsheet cell types.
