Frequently asked questions
Can I clean an Excel file that contains formulas?
Same-sheet ordinary A1 references in XLSX and XLSM are updated for row deletion and column deletion, insertion, and reordering. Other formulas require complete stored results and confirmation before becoming values.
How do original-text and safe CSV modes differ?
Original-text mode preserves values and warns about risky leading characters; it is not represented as safe. Safe mode prefixes affected values with an apostrophe.
Are files or results sent to a server?
No. Reading files, applying rules, and creating XLSX, CSV, and ZIP results happen in the current browser without modifying originals.
