Hi Ercan,
I understand that you want to use MATLAB to synchronize timestamps from different Excel spreadsheets, but the incorrectness of the second spreadsheet is a hindrance. To clean the second spreadsheet, you can apply some data cleaning techniques. Below are a few general steps:
1. If you suspect that some timestamps in the second spreadsheet are outliers or erroneous, you can identify and remove them.
2. If there are missing timestamps in the second spreadsheet, you can interpolate the missing values based on neighbouring timestamps.
3. If the timestamps in the second spreadsheet have formatting issues or inconsistencies, you can use string manipulation functions to correct them.
To get detailed information about Data Cleaning Techniques, please refer to the documentation below:
