Questions & limits
How can I check which delimiter a CSV file uses?
Choose Auto to let the checker detect comma, semicolon, tab, or pipe separators. If the preview still shows one long column or shifted data, select the delimiter manually and refresh the preview.
Can this tool fix garbled Chinese CSV text?
It can preview common UTF-8, GB18030, and Big5 encodings so you can identify the correct setting. It does not rewrite the source file; save a corrected copy in your spreadsheet application after confirming the encoding.
Are product and order files uploaded?
No. The selected CSV and Excel files are read in your current browser session. This tool does not upload the file contents to the Kindiv server.
Does the Excel preview recalculate formulas?
No. It displays cached formula results stored in the workbook. Open the file in Excel or another spreadsheet application when formulas need to be recalculated.
