How to resolve the error when importing result files in JMeter?

There could be several reasons for the error that occurs when importing results files into JMeter.

1. The result file format is incorrect. Please make sure the format of the result file is supported by JMeter, which is generally a file with a .jtl or .csv extension. If the file format is incorrect, please convert the result file to the correct format.
2. The result file path is incorrect: Please make sure that the result file path specified in JMeter is correct. Check if the path contains special characters, spaces, or if the folder doesn’t exist.
3. The result file is currently being used by another program: If the result file is being used by another program, such as Excel or another JMeter instance, please close the corresponding program and try importing the result file again.
4. JMeter version is not compatible: Make sure the version of JMeter you are using is compatible with the version of the result file. If the JMeter version is lower, try upgrading to the latest version or using a JMeter version that is compatible with the result file version.
5. If the output file is damaged: If the output file is corrupted or incomplete, try using a backup file or regenerate the output file.

If none of the above methods work, you can try reinstalling JMeter or asking for help on the official JMeter forum with detailed error information and steps taken, so other users can assist in solving the issue.
