How It Works
How to Convert CSV
Click inside the file drop area to upload your CSV file or drag & drop it.
Locate your CSV file on your device—typically used for various purposes. Ensure the file is under 50MB to avoid upload issues. If the upload fails, check your internet connection or try compressing the file first.
Choose the format you want to convert your CSV file to and click 'Convert'.
Choose your desired format based on your needs—different formats suit different purposes, like JPEG for smaller file sizes. The conversion process typically takes a few seconds, depending on file size and server load.
Download your converted file instantly after conversion.
Once the conversion is complete, click the download link to save your converted file. You can then open it in software like a compatible viewer. If the file doesn’t download, ensure your browser allows pop-ups from RunConvert.
You can also send a link to the converted file via email. (Optional)
Enter an email address to receive a secure link to your converted file, which is useful for sharing with clients or accessing later. Links expire after 24 hours for security, and RunConvert ensures your data is protected during transmission.

Q: Can RunConvert.com handle large CSV files?
A: You got it! RunConvert.com can manage most CSV sizes, though huge ones might take a moment. It’s like mailing a big package—it’ll get there, just give it a sec.
Q: How fast is CSV conversion on RunConvert.com?

Q: Is it safe to upload CSV files to RunConvert.com?
A: Totally safe. RunConvert.com uses top-tier encryption, like a digital vault for your data. Your numbers and notes are secure with us.
Q: What’s a CSV file, and why would I convert it?
A: A CSV, or Comma-Separated Values file, is like a bare-bones spreadsheet—simple text with data in rows and columns. You might convert it to XLSX or PDF to add formatting or share it professionally. RunConvert.com makes it a breeze to switch formats, like turning a rough sketch into a polished blueprint.
Q: Why are some formulas broken after converting?
A: Not all formats use the same formula syntax. Stick to XLSX or ODS for the best compatibility.
Q: Does RunConvert compress spreadsheet files?
A: We don’t compress them by default, but the resulting files are often smaller—especially if converting from XLS to XLSX or to CSV.
Q: Can I convert CSV files with semicolons instead of commas?
A: Yes! Our converter auto-detects separators. But if it doesn’t, just tweak the input settings when uploading.
Q: Can I remove empty columns before converting?
A: You’ll need to do that manually before uploading. We’re planning to add a cleanup tool in the future!
Q: What’s the safest format to share with non-tech users?
A: PDF is the safest—it's readable, uneditable, and works on almost every device without special software.
Q: Does RunConvert support TSV (tab-separated values)?
A: Yes! We support TSV both as input and output—it’s great for clean, plain-text spreadsheets.
What is CSV (Comma-Separated Values)?
CSV (Comma-Separated Values) is a simple text-based file format used for storing tabular data, such as spreadsheets or databases. Each line of a CSV file represents a row, and each value within a row is separated by a comma.
CSV files are commonly used for data exchange between different applications and are easily opened and edited by spreadsheet programs like Microsoft Excel, Google Sheets, and other data processing tools.
How to open CSV?
CSV files can be opened using spreadsheet programs such as Microsoft Excel, Google Sheets, or LibreOffice Calc. You can also open them using text editors like Notepad or Sublime Text, although they won't display the data in a table format.
To open CSV files in Excel or Google Sheets, simply double-click the file or import it into the application.
CSV is Developed by: International Organization for Standardization (ISO)
CSV was Released on: 1983
