Where does pipe-delimited (PSV) data usually come from?

Commonly from legacy database exports, mainframe systems, and data engineering pipelines, where pipes are chosen specifically because they rarely collide with real-world text content the way commas do.

Does it handle quoted fields containing pipes or commas?

Yes, the input is parsed with a full RFC 4180-aware parser, so quoted fields containing either character, or embedded newlines, convert correctly without breaking row structure.

Will row and column counts change?

No, only the delimiter character changes; every field maps 1:1 from the PSV input to the CSV output.

What if a field already contains a comma?

It gets wrapped in double quotes in the CSV output per RFC 4180, so it round-trips correctly and doesn't get mistaken for a new field boundary.

Is this just a global find-and-replace of pipes with commas?

No, a naive replace would also affect pipes that legitimately belong inside quoted values. This tool parses the PSV structurally first, so only actual field-separating pipes become commas.

Can I convert back to PSV afterward?

Yes, use the CSV to PSV converter, which reverses this exact conversion.

PSV to CSV Converter - Pipe to Comma

Overview

Introduction

Legacy database exports and data engineering pipelines often use pipe-delimited PSV instead of standard comma CSV, precisely because pipes rarely appear in real-world text. This tool converts that PSV back into standard comma CSV for tools that expect it.

It parses the PSV structurally first, so only genuine field-separating pipes are replaced, not pipes that legitimately belong inside quoted values.

What Is PSV to CSV Converter?

A delimiter-conversion tool that re-parses pipe-separated values and re-serializes the same rows and columns using commas as the field separator instead.

It's the direct inverse of the CSV to PSV converter in this category.

How PSV to CSV Converter Works

The input is parsed character by character with the pipe as the delimiter, correctly handling quoted fields that contain pipes, commas, or embedded newlines.

The resulting grid of cells is re-serialized using commas, with any cell containing a comma, quote, or newline automatically wrapped in quotes.

When To Use PSV to CSV Converter

Use it right after exporting or receiving pipe-delimited data from a legacy database or mainframe system, to get standard CSV for an API, script, or import tool.

It's also useful when a data pipeline standardized on PSV internally but needs to hand off to a system that only accepts comma CSV.

Often used alongside CSV to PSV Converter, SSV to CSV Converter and CSV Delimiter Changer.

Features

Advantages

Correctly handles RFC 4180 quoting, so quoted fields containing pipes or commas convert without corruption.
Preserves row and column structure exactly, only the delimiter character changes.
Runs entirely client-side, so your data never leaves the browser.

Limitations

Assumes the input is pipe-delimited; comma-, tab-, or semicolon-delimited input should go through the matching converter instead.
Doesn't attempt any other data cleanup, encoding fixes, or validation beyond changing the delimiter.

Examples

Converting a small PSV to CSV

Input

id|name|active
1|Ada Lovelace|true
2|Alan Turing|false

Output

id,name,active
1,Ada Lovelace,true
2,Alan Turing,false

Each pipe between fields becomes a comma; the row and column layout is otherwise unchanged.

Best Practices & Notes

Best Practices

Verify the input is genuinely pipe-delimited before converting, some exports mix delimiters across different fields or sections.
If your data legitimately contains pipe characters inside values, confirm they were properly quoted in the source PSV before converting.
Pair with CSV to PSV to confirm a round trip reproduces your original data.

Developer Notes

This is a two-step pipeline over the shared CSV grid parser: parse with `|` as the delimiter, then re-stringify the same grid with `,` as the delimiter. Both steps share the same RFC 4180-aware escaping logic used by every other delimiter converter in this category.

PSV to CSV Converter Use Cases

Converting a legacy database or mainframe pipe-delimited export into standard CSV for a modern API or script
Normalizing PSV data engineering output before handing it off to a comma-CSV-only downstream system
Preparing pipe-delimited data for import into a spreadsheet program that expects standard CSV

Common Mistakes

Assuming all pipe characters in the source were meant as delimiters; unquoted literal pipes inside values would have already broken the PSV structure before reaching this tool.
Running comma- or semicolon-delimited data through this tool expecting auto-detection; it always parses the input as pipe-delimited first.

Tips

If the output has more columns than expected, check the source PSV for unquoted literal pipe characters inside what should have been a single field.
Use CSV to PSV afterward on the result to sanity-check the round trip.
