CSV to Excel Converter
Convert CSV text into a downloadable Excel workbook (.xlsx).
A CSV opened straight into Excel is where phone numbers lose their leading zero, long IDs turn into 1.23457E+14, and 03/04 silently becomes March 4th or April 3rd depending on where the machine thinks it is. Converting to a real .xlsx first means you hand people a workbook instead of a text file that Excel is free to reinterpret on their machine.
How CSV to Excel Converter works
- Enter or paste your text or values.
- It's processed instantly on your device as you type.
- Copy or download the result.
Good to know: This uses the same type detection Excel does, so a column of values like 007 still arrives as 7. If a column must stay exactly as typed — PINs, phone numbers, account codes — prefix the values with an apostrophe before converting, or set that column to Text in Excel afterwards.
Common questions
Will my leading zeros survive?
Not automatically. Values that look numeric are read as numbers, which is what Excel itself does with a CSV. The reliable fix is to mark those values as text before converting — an apostrophe in front of each — or format the column as Text once the workbook is open.
Does it handle quoted fields and commas inside values?
Yes. Standard CSV quoting is parsed properly, so a field like "Mumbai, Maharashtra" stays one cell rather than splitting across two.
