What is SPSS CSV Formatter?

SPSS CSV Formatter reshapes a CSV so that SPSS will import it cleanly on the first attempt. SPSS is strict in ways spreadsheets are not: variable names cannot contain spaces or start with a digit, they are length-limited, missing values need a consistent representation rather than a mix of blanks and "N/A", and a header row that spans two lines will be read as data. This tool fixes those specific problems rather than doing general-purpose cleaning.

How to use SPSS CSV Formatter

1Upload or paste the CSV you plan to import into SPSS.
2Review the flagged variable names — spaces, leading digits, punctuation and over-length names.
3Apply the suggested renames, or edit them to match your codebook.
4Standardise how missing values are represented across the file.
5Download the reshaped CSV and import it into SPSS.

Features

Variable-name validation against SPSS naming rules
Suggested renames that stay readable rather than truncating blindly
Consistent missing-value representation across every column
Header-row problems detected before import rather than after
Runs in the browser, so participant data never leaves your machine
Download the corrected CSV ready for import

Common uses

Preparing survey exports for SPSS analysis
Fixing a CSV that SPSS imported as one long string column
Standardising missing-value codes across a questionnaire dataset
Cleaning variable names to match a codebook before analysis

Common errors

Variable names with spaces or starting with a digit — SPSS rejects both, and the failure message rarely says which variable caused it.
Mixed missing-value markers in one column (blank, NA, N/A, -99), which SPSS treats as distinct string values and which silently turns a numeric variable into a string one.
A two-row header from a survey export, where the second row becomes the first case.
Comma decimal separators in a comma-delimited file, which shifts every column after the first affected one.

How it works

1The header row is checked against SPSS variable naming rules, and each violation is reported with the specific rule it breaks.
2Column values are scanned for the set of distinct missing-value markers actually present, so they can be unified rather than guessed at.
3The corrected file is regenerated in your browser and offered as a download — nothing is uploaded.

Frequently asked questions

What are SPSS's variable naming rules?: Names must begin with a letter, contain no spaces or most punctuation, avoid reserved words like ALL and BY, and stay within the length limit (64 bytes in modern versions, 8 in very old ones). The tool flags each violation individually.
Why did SPSS import my numbers as strings?: Almost always a stray non-numeric value in the column — an "N/A", a currency symbol, or a thousands separator. One such value in ten thousand rows is enough to make the whole variable a string.
Is my participant data uploaded?: No. The file is read and rewritten entirely in your browser, which matters when the data is covered by an ethics approval that restricts where it can be processed.
Does this produce a .sav file?: No — it produces a clean CSV that SPSS can import without complaint. Saving as .sav is done inside SPSS once the data is in.
