Open tool Excel to CSV
Export the first or every XLSX worksheet to formula-protected UTF-8 CSV without executing formulas.
BUILT AROUND THE TASK
Clean and convert spreadsheet data
Move a spreadsheet export into the format your next system expects. Check duplicate records, align columns, and convert between CSV, Excel, and JSON while keeping field meanings intact.
USE WITH CONTEXT
Before you use these tools
Work on a sample first. Pay attention to leading zeros, date formats, decimal separators, blank cells, and quoted line breaks. Keep identifiers as text when converting them to numbers would change their meaning.
A PRACTICAL ROUTE THROUGH THE SHELF
From raw input to reviewed output
- 1
Inspect the source
Check the header row and a few representative records. Decide which fields identify duplicates before removing any records.
- 2
Match the destination
Map columns to the required names and order, then choose the delimiter or file format expected by the receiving system.
- 3
Reconcile the result
Compare record counts and spot-check dates, identifiers, and empty values. Test a small import before processing the complete dataset.

Questions before you start
Why do account numbers lose their leading zeros?
Spreadsheet software may interpret an identifier as a number. Treat account codes, postcodes, and similar fields as text, then check both the converted file and the import settings of the destination application.
