Convert CSV to Excel without interpreting formulas

Step-by-step approach

Inspect CSV delimiter, quoted commas and UTF-8 text.
Choose CSV to XLSX Workbook and load the source text.
The generated XLSX stores values as text, not formulas, preserving zero-prefixed IDs.
Open the result in Excel or LibreOffice and check a few rows.
If you need real dates, numeric types or formulas, configure them explicitly in your spreadsheet editor.

Try the matching tool

Open CSV to XLSX Workbook to work on a local copy. Review the result before importing it elsewhere.

What this does not solve

Browser tools can validate known structures and transform available data, but cannot restore deleted or corrupted bytes, infer unknown business facts, or guarantee that a target system will import every field as intended.
