FAQ

A: Four formats are supported: decimal (65 66 67), hexadecimal (0x41 0x42), binary (01000001), and octal (0101). You can use spaces, commas, or line breaks to separate values, and the system will automatically identify the format.

A: The valid range for standard ASCII codes is 0-127. Values 0-31 and 127 are control characters, while 32-126 are printable characters. Values outside this range will be marked as invalid, and error information will be displayed in the conversion details.

A: Control characters (0-31 and 127) are displayed in a special format, such as [NULL], [TAB], [LF], [CR], etc. These characters are not visible in actual text, but their specific meanings are shown in the conversion details table.

A: No. All ASCII conversion is completed locally on your device. Files and data are not uploaded to the server, ensuring your privacy and data security.

A: In theory, there is no limit on the number of files, but we recommend processing no more than 100 files at a time to ensure optimal performance. For large numbers of files, process them in batches. Each individual file should be no larger than 10MB.

A: Yes. Single conversions support copying the result and downloading it as a TXT file; batch conversions support downloading a ZIP archive containing all converted text files, making them easy to save and share.

A: Common reasons include: entering non-numeric characters, ASCII code values outside the 0-127 range, and format recognition errors. The system will display specific error information and location details in the conversion details to help you quickly identify the issue.

A: You can use the "Common ASCII Code Reference" table on the right, or click the quick input example buttons to view the ASCII codes for common characters. The conversion details will also show the decimal, hexadecimal, and binary mappings for each character.
