CSV Financial Data to Excel for Reports

Finance systems export CSV, but reviewers want a spreadsheet. Converting it keeps the values safe from Excel guessing.

Open the CSV to Excel converter and drop the export. Keep account codes as text so 001200 stays as it is, and turn on type detection for amounts and dates.

Excel gets a real .xlsx file with a bold, frozen header row. A sheet holds at most 1,048,576 rows, so check the row count first.

Check negative amounts and totals against the system report. For two periods, use Data Comparison to see which accounts changed before you build the review file.

Everything runs in your browser and nothing is uploaded.

Frequently asked questions

How do I convert CSV to Excel?

Drop your CSV file (or paste the data), check the options, click Convert and download the Excel result.

How big can a file be?

It depends on your device. A few hundred MB usually works.

Which conversions does the Format Converter support?

Any direction between JSON, CSV, Parquet and Excel (.xlsx), for one file or a whole folder. Nested JSON is flattened into columns such as address.city. For Excel, the first sheet is read; old .xls files are not supported.

Why did my number or date change after converting?

Types are detected from the values. Turn off "Detect types" to keep everything as text, which also keeps leading zeros in IDs and phone numbers.

Tip: Compare a total with the system report before you share the file.
