UTF-8 output, every time
Exported CSV is always UTF-8, so accented characters, non-Latin scripts, and symbols survive the trip into CRMs, databases, and import pipelines.
All use cases
Convert Excel to CSV without broken characters.
Saving an Excel file as CSV often mangles accented names, smart quotes, and non-Latin text, and a multi-sheet workbook only exports its active sheet. CSV Power Editor opens the XLSX, shows you every sheet in a real grid, and writes clean UTF-8 CSV — locally on your Mac, no Excel required.
How to
XLSX to CSV in five steps.
- 1
Open the Excel workbook
Launch CSV Power Editor and open the .xlsx file (File → Open, or drag it onto the window). Every worksheet appears as its own tab.
- 2
Pick the sheet to convert
Click the tab for the worksheet you want as CSV. A CSV file holds exactly one table, so each sheet you need becomes its own CSV file.
- 3
Clean the data first (optional)
Run Power Tools before exporting: trim stray spaces, remove blank rows, fix dates, split columns, or dedupe — each with a live preview before anything is applied.
- 4
Save As CSV
Choose File → Save As and select CSV as the format. The file is written as UTF-8 with correct quoting for commas, quotes, and line breaks inside cells.
- 5
Export only the rows you need (optional)
If filters are active, use Save Filtered to write just the visible rows to a new CSV instead of the whole sheet.
Why it works
What makes the output import-safe.
Correct quoting and escaping
Cells containing commas, double quotes, or line breaks are quoted and escaped automatically, so downstream parsers read the file without shifted columns.
Multi-sheet workbooks handled honestly
CSV is a single-table format. CSV Power Editor shows all sheets as tabs so you can export each one deliberately instead of silently losing everything but the active sheet.
Preview before you commit
You see the full grid — headers, row counts, and values — before saving, and every cleanup step shows affected rows first. No blind conversions.
FAQ
Common questions.
Will accented characters and non-English text survive the conversion?
Yes. CSV Power Editor always writes CSV as UTF-8, which preserves accented characters, Cyrillic, Arabic, CJK text, and symbols. This avoids the classic Excel problem where Save As CSV produces question marks or garbled characters.
How do I convert an Excel workbook with multiple sheets to CSV?
Open the workbook and each worksheet appears as a tab. Select a tab and use Save As to write it as CSV, then repeat for the other sheets you need. CSV holds one table per file, so this gives you one clean CSV per sheet.
Can I convert only some rows of the spreadsheet?
Yes. Apply column filters to the grid, then use Save Filtered to export only the visible rows to a new CSV file.
Does converting change my original Excel file?
No. Save As writes a new CSV file and leaves the original .xlsx untouched.
Do I need Microsoft Excel installed?
No. CSV Power Editor reads and writes XLSX natively on your Mac. Files never leave your machine — there are no cloud uploads.
Is it free?
The app is free to download with a 14-day full Pro trial. After the trial, free mode keeps files up to 300 rows fully editable, and a one-time $14.99 Lifetime Pro purchase unlocks larger files.
