Convert Excel to CSV on iPhone, iPad, and Android — Free, No App Install
Table of Contents
You have an Excel file on your phone. You need a CSV. Most guides tell you to open it on a computer first — but that's not always an option, and it shouldn't be required.
The good news: you can convert Excel to CSV directly on your iPhone, iPad, or Android device, right in your browser. No app to install, no account to create, no file uploaded anywhere. It works in Safari, Chrome, Firefox — whatever browser you're already using.
Why Browser Tools Work on Any Device
The tool runs entirely in your browser using your device's built-in processing power. The file never leaves your phone or tablet — no server upload, no cloud processing, just your device doing the conversion locally.
That means iPhone users running Safari get the same result as Chrome on Android. As long as you have a modern browser (any version from the last few years works), you're good to go.
This also means your file is private. Customer lists, financial data, employee records — none of it touches a server. Once you close the tab, it's gone.
How to Convert Excel to CSV on iPhone or iPad
Open Safari (or Chrome) on your iPhone or iPad and navigate to the Excel to CSV converter.
- Tap the drop zone. This opens your Files app. Navigate to the .xlsx or .xls file you want to convert — it can be in iCloud Drive, On My iPhone, or any connected storage.
- Select your sheet. If your workbook has multiple sheets, a sheet picker appears. Tap the sheet you want to convert.
- Preview the data. You'll see the first several rows of your CSV in the preview area. Verify the columns look right.
- Tap "Download CSV." Safari downloads the file to your Downloads folder (accessible from the Files app). You can also tap "Copy" to paste the CSV text directly into another app.
If you have a multi-sheet workbook and need every sheet as a separate CSV, tap "Download All Sheets" instead. Each sheet downloads as its own file.

How to Convert Excel to CSV on Android
Android works the same way. Open Chrome (or any browser) and go to the Excel to CSV tool.
- Tap the drop zone. Your device's file picker opens. Navigate to your .xlsx file — in Google Drive, Samsung Files, or local storage.
- Pick your sheet. Multi-sheet files show a dropdown. Tap the sheet you want.
- Download or copy. Tap "Download CSV" to save it to your Downloads folder, or "Copy" to grab the raw CSV text.
One Android-specific note: if your browser prompts you about downloading files, tap "Allow" when asked. Chrome on Android handles .csv downloads cleanly — the file opens in Sheets or any compatible app after download.
Also supports .xls (old Excel format) and .ods (OpenDocument). If you're working with legacy files from an older system, those work fine too.

The trickiest scenario on mobile is a workbook with 10 or 15 sheets and you need specific ones as CSVs. Here's the fastest workflow:
- Load the file once.
- Use the sheet dropdown to select Sheet 1 → tap Download CSV.
- Tap "Load Another" — this resets without losing your file reference on most mobile browsers.
- Actually, even faster: use "Download All Sheets." One tap gives you a separate CSV for every sheet in the workbook.
The "Download All Sheets" button is the mobile power move. Instead of repeating the process per sheet, one tap downloads everything. On iPhone, the files go into your Downloads folder. On Android, they land in your Downloads directory.
Common Issues and How to Fix Them
"The file picker shows nothing." On iPhone, make sure you're looking in the right location in the Files app. Files shared from email or messages are often in "From [App Name]" rather than a standard folder.
"My CSV downloaded but I can't find it." On iPhone: open the Files app and check the Downloads folder under "On My iPhone." On Android: open your file manager or the Downloads app.
"The columns look wrong in the preview." This usually means your data has embedded commas. The tool uses proper RFC 4180 CSV formatting (quoted fields), so it should handle commas in data correctly. If something still looks off, double-check the source Excel file.
And if you're ultimately trying to get data into Google Sheets, there's a shortcut: once you have the CSV file, open Google Sheets on your phone and use File → Import to bring it in directly.
Other Spreadsheet Conversions That Work on Mobile
The browser-based approach applies to the whole spreadsheet toolkit, not just Excel-to-CSV. All of these work on your phone or tablet:
- CSV to Excel — reverse direction, convert CSV back to .xlsx
- Excel to JSON — export your data as a JSON array, useful for developers
- Excel Viewer — open and inspect .xlsx files without converting, sort and search columns
- Excel to HTML Table — convert your spreadsheet data to a styled HTML table for websites
None of them require an app install. All of them work in Safari and Chrome on any device.
If you're frequently converting between formats, it's worth bookmarking the main Excel to CSV guide for reference — it covers the desktop workflow and additional format considerations.
