FAQ
Does it support both CSV and JSON formats?
Yes. Our tool automatically recognizes and processes data in both comma separated (CSV) and structured string format (JSON).
Will I lose data when changing headers?
No. The tool only changes the 'key' or 'header' names. Your data inside the cells is protected without any changes.
Can I process large data files?
For browser-based performance, you can handle data sets up to 5-10 MB without any problems. For larger files, it is recommended to upload data in chunks.
Can I use Turkish characters?
Yes, you can use Turkish characters or special symbols in new title names; However, we recommend that you make sure that the target system (e.g. a database or software) to which you will transfer your data supports these characters.
