Guides
The things people do most often with CsvDrill, step by step and with screenshots. Opening a large file and reading a garbled file with the right encoding work in the free version; splitting and converting are Pro.
Open a large CSV file that Excel can't open
Open a CSV file beyond Excel's 1,048,576-row limit without splitting it, uploading it or changing it.
Split a large CSV file into smaller files (Pro)
Split a file into parts that fit in Excel, or into separate files by the value of a column such as city or month; every part keeps the header row.
Fix garbled characters in a CSV file
Garbled letters come from the wrong encoding: choose the right one to read the file correctly, and create a UTF-8 copy or an .xlsx for a lasting fix.
