As instructed the **first column** of the imported file **must contain dates**. The columns contain the topics and the rows the measurements for the specified date. Like: | Date | Plant height | Number of leaves | Number of flowers | | --- | --- | --- | --- | | 23-01-2024 | 10 | 2 | 0 |   #### Example file [Download here an example file](https://30mhz.com/wp-content/uploads/2024/04/Example-sheet-Freesia-DD-MM-YYYY.csv) with date notation DD-MM-YYYY [Download here an example file](https://30mhz.com/wp-content/uploads/2024/04/Example-sheet-Freesia-MM-DD-YYYY.csv) with date notation MM-DD-YYYY #### Date notation For successfully importing your data, it is crucial that your uploaded file starts with a column designated for dates. This is because our system organizes and stores data based on these date values. Without this information, we are unable to save your data. Please ensure that each entry in your file is marked with a date in a consistent format to avoid any issues with data processing. Our system recognize most date formatting. You can check in the preview if we interpreted your dates correctly.  ![](https://support.30mhz.com/hs-fs/hubfs/image-png-Apr-25-2024-10-31-00-4050-AM.png?width=688&height=170&name=image-png-Apr-25-2024-10-31-00-4050-AM.png) #### Columns: type - unit You can change the name of the columns if you want. *Tip: don't use any metrics in the column names since this can be confusing when you later want to convert this metric to another one.*  For each column you need to select the type. Each type comes with a default unit, for some you can switch this default unit to another one. For example for length the default unit is mm, but you can also switch to cm, m and km.  ![](https://support.30mhz.com/hs-fs/hubfs/image-png-Apr-25-2024-11-27-06-8056-AM.png?width=353&height=195&name=image-png-Apr-25-2024-11-27-06-8056-AM.png) Can't find the type or unit you're looking for? Send a message to [support@30mhz.com](mailto:support@30mhz.com).  #### Timestamp The timestamp is the visual representation of the date / time in your sheet. You can switch this to whatever you like (it's not dependent on the date format in your original sheet). ### Save imported data If you selected a type for each column and the preview is looking good you can save the data via the 'Save' button in the top right corner. Your new form opens up. Don't worry if you see an empty form. **Try a refresh**. ![](https://support.30mhz.com/hs-fs/hubfs/refresh-111%201-png.png?width=17&height=17&name=refresh-111%201-png.png) As the expandable info message says it can take **up till 10 minutes** before your data is visible (depending on the amount of data).  ![](https://support.30mhz.com/hs-fs/hubfs/image-png-Apr-25-2024-11-39-06-9440-AM.png?width=688&height=170&name=image-png-Apr-25-2024-11-39-06-9440-AM.png) #### No data in your imported form?
