FAQ
Does csv to excel send my input to a server?
No. CSV to Excel handles the input in your browser whenever possible, so routine conversions, previews, and copy actions stay on your device instead of being sent to Calctrove servers.
Does it support quoted CSV fields?
Yes. It supports delimiters, escaped quotes, and line breaks inside quoted fields.
Why are some columns shifted?
Most shifts come from malformed row delimiters or unbalanced quotes in CSV input.
Will IDs and CSV formulas be changed?
Leading-zero identifiers and formula-like values are preserved as text instead of being executed.
