Edit XLSX Columns Online — Delete, Rename and Reorder Without Opening Excel
Table of Contents
Excel XLSX files are everywhere — exported from business tools, shared by clients, generated by automated reports. But not everyone has Excel installed, and even when you do, opening a large XLSX file just to delete a few columns and save is overkill.
A free browser-based column editor handles XLSX files directly — no Excel license, no Google Sheets upload, no server. Open the file, edit the columns, download the result.
Why You Might Need to Edit XLSX Without Excel
- You are on a Mac or Linux machine and do not have Excel — only LibreOffice or Numbers
- You are on a Chromebook where Excel is not available as a desktop app
- You want to avoid uploading the file to Google Sheets for privacy reasons
- Excel is slow to open for large files and you just need a quick column edit
- The file was shared from a Windows user and you are on a different OS
How to Edit XLSX Columns in Your Browser
- Open the free column editor in your browser.
- Click the upload area or drag your XLSX file into it.
- If the file has multiple sheets, select which sheet to work with.
- All column headers appear as a list with checkboxes and name fields.
- Uncheck columns to delete, click names to rename, use arrows to reorder.
- Click Download — choose CSV or XLSX as your output format.
Multi-Sheet XLSX Support
The tool handles multi-sheet Excel files. After uploading, you can select which sheet to work on. The column operations apply to the selected sheet's data. This covers the majority of real-world XLSX files that have data spread across multiple tabs.
Output: CSV or XLSX?
After editing your columns, you can download the result in either format:
- CSV — the most portable format. Works with any spreadsheet app, database import tool, or data pipeline. Loses multi-sheet structure (outputs one sheet).
- XLSX — preserves the Excel format. Use this if the recipient expects an Excel file or if you plan to open it in Excel or Google Sheets afterward.
For most data processing or import use cases, CSV is the better choice.

Open Free Column EditorFrequently Asked Questions
Does this work with password-protected XLSX files?
No. The tool cannot open password-protected Excel files. You would need to remove the password protection in Excel or LibreOffice first.
Can I edit multiple sheets at once?
No. The tool works on one sheet per session. If you need to edit columns across multiple sheets, process each sheet separately.
Is this the same as editing the file in Google Sheets?
Functionally similar for column edits, but with a key difference: Google Sheets uploads your file to Google's servers. This browser tool processes everything locally — your file never leaves your device.
Does it support the old .xls format?
Yes. The tool accepts both .xlsx (modern) and .xls (legacy) Excel formats.
