How To Convert Unix Timestamp To Date In Excel

Introduction

Converting a Unix timestamp to a readable date format in Excel can be essential for data analysis and reporting. This process involves using built-in functions or formulas to translate the Unix time, which counts seconds since January 1, 1970, into a conventional date and time.

While Excel requires complex formulas and manual steps for this conversion, there's a simpler solution using AI. We'll show you the traditional Excel method and demonstrate how Sourcetable's AI chatbot can instantly handle Unix timestamp conversions, data analysis, and visualizations - just sign up for Sourcetable to try it yourself.

Convert Unix Timestamp to Date in Excel

Understanding Time Systems in Excel

Excel and Unix measure time differently. Excel's zero-time is January 1, 1900, while Unix's zero-time starts from January 1, 1970. This discrepancy requires an adjustment for accurate conversion.

Converting Unix Seconds to Excel Date

To convert seconds from the Unix epoch to an Excel date format, divide by 86,400 to convert seconds to days. Then add 25,569 to align with Excel's zero-time. Use the formula =A1/86400 + 25569, replacing A1 with your Unix timestamp cell.

Converting Unix Milliseconds to Excel Date

When dealing with milliseconds, divide the Unix timestamp by 86,400,000 and add 25,569. Apply the formula =(A1/86400/1000)+25569 in Excel, where A1 is the cell with your Unix timestamp.

Using Excel's DATE Function

Excel provides a DATE function to simplify the conversion. For seconds, use =A1/(24*60*60) + DATE(1970,1,1). This automatically adjusts for the epoch difference and converts to a date.

Limitations

Excel supports dates up to December 31, 9999. Ensure that your Unix timestamp falls within Excel's date range limitations.
