Frequently Asked Questions
Here are some common questions and answers about csv file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Can I convert a spreadsheet into JSON or XML?
A: RunConvert doesn’t support that just yet, but it’s on the roadmap. For now, you can use tools like Excel-to-JSON converters online.
Q: Can I convert password-protected Excel files?
A: You'll need to remove the password first. Conversion tools can’t peek inside locked files—privacy, remember?
Q: Can I open a converted CSV on Google Sheets?
A: Of course! Just drag and drop the file into Google Drive and open with Sheets. Works like a charm.
Q: How do I know if the converted file is accurate?
A: We recommend opening and scanning the result before sharing. Most conversions are spot-on, but it’s good to double-check!
Q: What if I accidentally upload the wrong file?
A: No stress—just hit back and upload the right one. We don’t store anything, so no damage done.
Q: What’s the most universal spreadsheet format?
A: CSV, hands down. It’s readable by almost every spreadsheet program, script, and database. It’s the Swiss Army knife of spreadsheet formats.
Q: How do I convert a spreadsheet with password protection?
A: You’ll need to remove the password before uploading. RunConvert can’t convert protected files—for your security!
Q: Do formulas still calculate after converting XLSX to ODS?
A: In most cases, yes. Excel and LibreOffice play nicely together—but complex macros or newer functions might act up a bit.
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.
Q: Will text wrapping be preserved after conversion?
A: Yes, as long as the format supports it. PDF, XLSX, and ODS usually preserve wrapping. CSV won’t.
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
