Tool usage guide
The XLSX CSV Batch Converter is a professional utility designed to streamline spreadsheet format transitions, allowing you to convert between CSV, TSV, and XLSX files in bulk while managing complex text encodings and delimiters.
Background
A data analyst has 20 separate CSV files exported from a web tool that need to be compiled into a single Excel report.
Problem
Manually opening and copying data from 20 files is inefficient and prone to error.
How to use
Upload all 20 CSV files, set the mode to 'CSV/TSV to XLSX', and enable 'Always Return ZIP'.
Outcome
The tool processes all files and returns a single ZIP archive containing the converted XLSX files, ready for immediate use.
Background
A marketing manager needs to upload a customer list from an Excel file into a CRM system that only accepts CSV.
Problem
Standard Excel exports often cause encoding issues with non-English characters in the CRM.
How to use
Upload the XLSX file, select 'XLSX to CSV/TSV', and set the 'Output Encoding' to 'UTF-8 with BOM'.
Outcome
A clean CSV file is generated that maintains character integrity, ensuring a successful import into the CRM.
Yes, the tool supports batch processing for up to 50 files simultaneously.
Select the correct 'Source Text Encoding' (e.g., UTF-8, GBK, or Shift_JIS) that matches your original file to resolve character display issues.
Yes, you can specify 'Tab' as the input or output delimiter to handle TSV files correctly.
Using UTF-8 with BOM is recommended when exporting to CSV to ensure that spreadsheet applications like Excel correctly recognize the file encoding and display special characters properly.
The tool supports individual file uploads up to 100MB.
